Trucking Shoulder Accidents and Safety Protocols

Stopping on the side of the road, especially on the highway, is inherently dangerous. In 2022, according to the Federal Motor Carrier Safety Administration, 40% of fatal crashes involving large trucks occurred on interstate highways. When a vehicle is stopped in a high-speed area, there is a risk of danger, especially during bad weather or at night. Traveling at high speeds decreases the reaction time of drivers and often leads to large swerves to try to avoid a crash.

Semi-trucks stopped on the shoulder of the road pose a large issue as they take up much of the shoulder, and sometimes take up space in the lane. Federal and state law enforce strict guidelines on lighting and emergency triangle use in an attempt to give drivers in oncoming traffic a heads-up on the stopped vehicle ahead.

Given the severity of trucking accidents, there are strict safety regulations required by drivers when they need to pull over to the shoulder of the road, and when it is in operation. State and federal guidelines require that lighting and emergency triangles are in effect to allow for maximum visibility of a semi-truck pulled over on the roadway. The binding law in the Code of Federal Regulations is 49 CFR 392.22, which outlines regulations for stopped commercial motor vehicles.

The Reason for Semi-Trucks to Be Stopped

When the driver of a large truck stops, the reason matters when deciding to employ emergency signals. If the driver is stopped for traffic reasons like congestion, a red light, or police direction, no emergency signals need to be employed. If the driver stops because of vehicle troubles, a load check, fatigue, or anything not related to traffic, they are required to employ their emergency signals.

These four-way flashers must be in operation. In broad daylight, the vehicle may be visible, but oncoming traffic is not expecting a vehicle to be stopped near the roadway. Flashing lights give drivers up to five hundred feet away a warning of the hazard ahead. Further, during nighttime or bad weather, visibility is low, so flashing red lights are helpful aids to notify oncoming traffic of the stopped semi-truck.

Federal Trucking Regulations 49 CFR 392.22

As there are various reasons for a stop, anything not traffic-related requires the use of four-way flashers and reflective emergency triangles. The driver must activate hazard warning signal flashers and put out three reflective triangles as soon as possible, but at least within ten minutes of being stopped.

Simply putting on flashers and emergency reflective triangles signals to oncoming traffic that there is a hazard, and they should stay within their lane to ensure they do not collide with the stopped commercial vehicle.

The truck driver should keep the flashers on until they place the emergency triangles around their vehicle. They should continue using the flashers when putting said triangles away. One triangle should be placed about ten feet from the commercial vehicle on the traffic side in the direction approaching traffic, so the reflectors are visible. The second emergency triangle should be placed about one hundred feet behind the commercial vehicle on the shoulder facing traffic. The third and last triangle should be placed one hundred feet in front of the commercial vehicle, which should be facing away from approaching traffic.

Trucks only equipped with liquid-burning flares follow the same rules as those with emergency triangles. They place one lit flare at the same locations as the triangles and keep them lit for as long as they are stopped. But if the commercial vehicle is experiencing any type of leak and is only equipped with liquid flares, they should not use the flares, as they can cause a fire.

If a commercial vehicle is stopped within five hundred feet of a hill, curve, or any type of obstruction of view from oncoming traffic, the warning devices should be placed one hundred to five hundred feet away from the vehicle to provide visibility to oncoming traffic. If the roadway is divided or a one-way, two emergency triangles should be placed toward oncoming traffic and one in the rear of the vehicle on the traffic side.

Regardless of night or day, when a commercial vehicle is stopped, the driver is required by law to employ hazard lighting and emergency triangles or flares.

The Timeline of Danger: Why the First 10 Minutes Are Critical

When a commercial vehicle breaks down on an Ohio highway, the clock immediately begins ticking for the truck driver. Under federal law, a driver has a strict 10-minute window from the moment they stop to fully deploy their reflective triangles or flares. This timeframe is a frequent battleground in personal injury lawsuits.

If a crash occurs seven minutes after a truck pulls over, and the driver has not yet placed their warning devices, the trucking company’s defense will argue they were still within the legal grace period. However, a skilled attorney will investigate whether the driver immediately activated their hazard flashers upon stopping, which is required instantly and without delay. Electronic logging data can pinpoint the exact second the wheels stopped moving.

Required Safety Warning Devices for Truckers

Under 49 CFR 393.95, a commercial vehicle must be equipped with three bidirectional reflective triangles that meet FMVSS 125 standards. While this equipment is the common standard, truckers may also opt for six fusees or three liquid-burning flares with the capacity to burn for at least 30 minutes—plus a spare. In addition to these emergency warning devices, there are additional rules that govern safety equipment, including federal lighting requirements.

Federal Lighting Requirements for Large Commercial Vehicles

Many commercial trucks operate during dark or nighttime hours. Proper lighting in low-light conditions is essential for the safety of the driver and others on the road. As there are different models and sizes of commercial vehicles, simple headlight and taillight rules are not adequate. The Department of Transportation has commercial vehicle lighting rules motor carriers must follow.

DOT vehicles are required to have:

Dual license plate lights in white
Two rear stop lights in red
Side marker lights in amber at the front and rear corners of the trailer
Reflectors on every corner
Two turn signal lights in amber
A clearance light on both sides of the trailer

No load or design should prohibit the visibility of any of the required lighting above. All lights should be working, bright, and visible from at least five hundred feet away from the truck.

For vehicles that are eighty inches or six and a half feet in width, they must include side markers and reflectors. The side markers must be amber, and reflectors must be white or red. Unlike the lights, they must be visible from at least fifty feet.

According to 49 CFR 393.11, the Federal Motor Carrier Safety Regulations require tractor-trailers to have standard operational lighting. Meaning, there must be working headlamps, tail lamps, stop lamps, turn signal lamps, clearance lamps, side-marker lamps, and reflex reflectors. All lights need to be placed properly, depending on the vehicle model and width. Such lighting must meet the standard outlined in 49 CFR 571.108.

It is very important that commercial vehicles have the proper lighting and reflective tape. The National Highway Traffic Safety Administration conducted a technical report on the effectiveness of retroreflective tape on heavy trailers. The NHTSA found that reflective tape prevents 7,800 crashes per year, which saves hundreds of lives and prevents thousands of injuries.

The FMCSA Requires Annual Safety Inspections

FMCSA requires annual inspections for vehicles weighing over ten thousand pounds. In order to pass this comprehensive safety inspection, qualified inspectors check critical vehicle components to ensure safe operations on public roads, including:

Brakes: Inspectors check linings, drums, and air lines to prevent catastrophic brake fade or total failure at high speeds.
Steering: Mechanisms are tested for excessive play or worn joints that could cause a driver to lose control and veer into the shoulder.
Lights and Reflectors: Functional headlamps, turn signals, and clearance lights ensure the massive vehicle remains highly visible in low-light conditions.
Tires and Wheels: Checks for tread depth, sidewall cracks, and secure lug nuts prevent dangerous highway blowouts and wheel-offs.
Coupling Devices: Fifth wheels and hitching systems are inspected to guarantee the trailer does not detach from the tractor during transit.
Suspension: Axles and leaf springs are evaluated to prevent structural collapses that can cause a truck to roll over or stall mid-trip.
Frame and Body: The structural integrity of the chassis is verified to ensure it can support heavy loads without buckling on the road.
Fuel Systems: Tanks and fuel lines are checked for leaks to eliminate the risk of devastating, post-crash fires on the roadside.

The driver of the truck is also required to conduct pre-trip inspections of their load and vehicle, as well as post-trip inspections. This inspection includes checking lighting. If a vehicle operator fails to complete either inspection, they face penalties that could lead to steep daily fines or out-of-service orders. But the real concern here is that they are placing themselves and others on the road in an unsafe position, which constitutes negligence.

Best Practices for Commercial Truck Drivers

As the drivers of commercial vehicles are required to go through rigorous training to ensure they can properly operate their vehicles, there are some good practices that they should, but are not required to, follow, especially when pulling onto the shoulder of the road.

Pull off onto the shoulder, away from the road as much as possible, and turn the wheels away from traffic. As these vehicles are very large, there is a possibility that the truck is in traffic while stopped. If the vehicle is in the roadway, it causes a huge hazard to oncoming traffic, as they are not expecting a non-moving vehicle in the middle of the road.
If conditions are unsafe, it is important to stay in the cab and call 911 or roadside assistance. For example, if the person is stopped for a load check and there is heavy, fast-moving traffic, they should wait in their vehicle until it is safe to conduct the load check.
Wear a high-visibility vest. As oncoming traffic is not expecting a non-moving vehicle on the highway, they are not expecting a person in the roadway. Having clothing on that reflects against the light makes a figure easier to identify.
Avoid standing between the truck and traffic. Try to stay on the safe side of the truck, as oncoming traffic is fast and not expecting a person to be in the roadway or near it.

Insufficient Parking Space: A Case Study

In 2023, there was a fatal Greyhound bus crash that killed three people and injured twelve. A Greyhound bus was exiting Interstate 70 in Springfield, Illinois, when it hit three semitrailers parked on the shoulder of the road. The first issue was the illegal parking. The trucks were parked illegally on a rest stop entrance and exit ramp, but the ban is not enforced seriously because of the insufficient parking for truck drivers.

There are thirteen million trucks on America’s roads, but not enough parking to support their rest hours. To support this further, the driver of the Greyhound bus was cited because of his fatigue while driving. But the three semi-trucks did not have any lighting or emergency triangles to indicate that they were stopped on the shoulder.

All in all, truck driving is very unsafe as the people operating the vehicles are not obtaining rest times, which leads to fatal crashes and injuries. Further, is it important to have lighting on vehicles not only parked in a location where drivers may not anticipate it to be, but in general.

Key Importance of Lighting Standards

As large semi-trucks and trailers dominate the road, guidelines and requirements set by the Federal Motor Carrier Safety Administration are made with purpose.

Enhanced Visibility:

For the safety of the driver and others on the road, working headlights, side load lights, and taillights need to be operational. In broad daylight, a semi-truck may be visible, but in fog, rain, or dusk, the truck may be difficult to see. The purpose of the red lights and markers is to be visible in such weather conditions. The white light can sometimes get lost in fog or mist, but red light can penetrate through such conditions.

Indication of Size:

Semi-trucks can vary in size based on their loads. The clearance markers and lights are helpful to drivers driving alongside or near a semi-truck to ensure a safe clearing distance when switching lanes or turning near a semi-truck.

Accident Prevention:

All in all, the more lighting and reflectors, the better. It’s similar to when you’re driving on the road, and a car passes you without its lights on at nighttime. You may have seen them up close, but not five hundred feet away. Now, instead of a sedan, imagine a two-ton load without any lighting, driving sixty miles per hour on the highway at night. With any vehicle, but especially those of the size of semi-trucks and trailers, they must abide by the rules mandated by the Federal Motor Carrier Safety Administration.

Does Ohio Have Statewide Windshield and Lighting Restrictions?

Yes. The state of Ohio has specific windshield and lighting regulations for commercial vehicles and trucks. The laws that govern these limitations fall under the Ohio Revised Code (ORC) Chapter 4513 and the Ohio Administrative Code Chapter 4501-41. These regulations state that:

Wiper-Activated Headlights: Truckers must turn on their headlights and taillights whenever windshield wipers are in use due to rain, snow, or fog.
Standard Usage: Exterior lights must be illuminated from sunset to sunrise, and whenever natural light or weather conditions make visibility poor.
Commercial Vehicle Clearance: Commercial trucks and tractor trailers must maintain visible clearance lights, identification lamps, side markers, and reflectors as outlined by the state, in addition to federal standards.
Color Restrictions: Front-facing lights are restricted to white or amber, and rear-facing mandatory lights and reflectors must display red. However, there are exceptions for specific emergency and plow equipment.

What About Trucker Windshield Light Violation?

Truckers can be subject to penalties for displaying non-factory windshield decorations like “angry eyes” and programmable LED strip lights. While these lighting systems are popular with some drivers, they are illegal for use on public roads in Ohio under the O.R.C. § 4513.17. This local law states that front-facing vehicle lights are strictly limited to white or amber, and flashing, oscillating, or colored graphic displays are strictly prohibited.

Trucker windshield light violations can occur with the use of programmable moving graphics, scrolling text, or blinking animation modes. These lights conflict with Ohio restrictions against non-emergency flashing or rotating windshield visuals.

Some professional drivers may utilize these devices temporarily at truck shows or static meets, operating the vehicle with them illuminated on active highways is risky. Commercial vehicle enforcement and Ohio’s highway patrol troopers are within their legal rights to pull over and cite drivers for illegal forward-facing colored or distracting ornamental displays, leading to failed roadside inspections and minor misdemeanor fines.

Potential Penalties for Local and Federal Violations

Truck drivers who fail to abide by the mandated regulations set by the FMCSA can face penalties. If a driver’s turn signals, license plate lights, taillights, or headlights are not performing as they should, the driver should anticipate being pulled over for such a violation.

Standard minor misdemeanor citations for defective or missing commercial lights can come with court fines from $50 to $250, depending on the specific municipal or county jurisdiction.
Defective or inoperative required lamps can add up to six points on the driver’s driving record. However, equipment violations typically do not add points to a commercial driver’s license in Ohio unless they involve unsafe operation or specific moving infractions.
When a driver has accumulated twelve points on their standard license within two years, they receive a six-month suspension for both the standard license and the CDL trucking license.
Under joint federal-state compliance, critical inoperative lamps can trigger an immediate out-of-service order, halting the vehicle until proper repairs are made.

According to Overdrive Magazine, Ohio is ranked number five as one of the toughest states on lighting violations. Lighting violations make up 22% of Ohio’s written infractions for heavy-weight vehicles.

As there are strict guidelines to drive a semi-truck or trailer, there are strict guidelines to keep them up and running safely on the roadway. The FMCSA has worked to make safe mandated rules and regulations relating to, but not limited to, the lighting and warning precautions required while driving and stopping a heavy hauling vehicle. Proper lighting and warning triangles are required for the purpose of keeping all drivers safe. In Ohio, we value upholding such regulations, but accidents still occur.

What Happens When the Negligence of Others Causes an Accident?

The importance of lighting and emergency triangles is to make your vehicle visible to oncoming and moving traffic. Our office has had numerous cases where our client, a commercially licensed truck driver, has been pulled over onto the shoulder of the road and been hit by oncoming traffic, even when our client has taken the proper steps to express caution.

For instance, our office had a case where our client was driving a tractor-trailer and pulled onto the shoulder of the road because of engine trouble. The defendant in the case was driving an oversized load, failed to see the four-way flashers employed by our client, and collided with him. As our client was under the vehicle at the time, he was thrown into the nearby ditch and experienced life-altering injuries.

There are many precautions to try to avoid such collisions. But they do occur, and one case has left our client with extreme anxiety and physical disabilities.

In Ohio, there are several factors to note when considering the negligence of others, including:

Assured Clear Distance Ahead

Under O.R.C § 4511.21(A), motorists must drive at a speed that lets them stop within the clear distance ahead. Striking a truck stopped on the shoulder establishes a strong presumption of the other driver’s fault. However, this legal presumption shifts entirely if the stalled truck was not “reasonably discernible” to an attentive motorist.

If a trucking company fails to deploy mandatory reflective triangles or has broken lighting standards, an oncoming driver cannot safely perceive the massive obstruction in time to react. In these complex cases, personal injury lawyers use the lack of visibility to overcome the standard assured clear distance defense and hold the negligent trucking operation liable.

The Move Over Law

Liability in a shoulder accident does not always rest solely on the truck driver. Understanding Ohio Revised Code § 4511.213 or the “Move Over Law” is essential. It requires all motorists to shift over one lane, if it is safe to do so, when approaching any vehicle stopped on the roadside with its hazard lights flashing.

If a lane change is impossible due to traffic, drivers must reduce their speed significantly. If a passenger vehicle strikes a stopped semi-truck because the driver failed to move over or slow down, that driver may be found comparatively negligent. This law highlights why analyzing the actions of all parties involved is vital to establishing fault.

Modified Comparative Fault

Ohio uses a 51 percent rule that allows you to recover damages as long as you are 50 percent or less at fault for the trucking shoulder accident. Unfortunately, your total compensation decreases by your exact share of blame, and if you were responsible for more than half the fault, you cannot file a claim for damages.
