Who is Responsible if a Commercial Truck Hits a Bicyclist?
As urban centers push for greener transportation, thousands of miles of bicycle lanes have been painted alongside busy city streets. Unfortunately, these lanes force unprotected cyclists to share the road directly with massive commercial vehicles, including 80,000-pound semi-trucks, concrete mixers, and Amazon delivery vans. When a collision occurs between a heavy commercial truck and a bicycle, the result is rarely a minor injury; it is almost always catastrophic, resulting in amputations, traumatic brain injuries, or death.
Because cyclists lack the steel cage of a passenger car, the physical damage is devastating. However, the legal battle that follows is equally brutal. Trucking insurance companies will aggressively blame the cyclist, claiming they darted into the truck's blind spot or ignored traffic signals. Determining exactly who is responsible if a commercial truck hits a bicyclist requires a precise understanding of urban traffic laws and commercial vehicle blind spots.
The most common and lethal truck-bicycle accident is the "Right Hook." This occurs when a commercial truck and a cyclist are traveling in the same direction, with the cyclist in the right-hand bike lane. The truck approaches an intersection and turns right, cutting directly across the bike lane and crushing the cyclist under the rear trailer wheels. In almost every state, a vehicle turning across a dedicated bike lane must yield to the cyclist. If the truck fails to yield, the motor carrier is 100% liable.
Defeating the "Blind Spot" Defense
The standard defense used by every commercial insurance adjuster is: "The cyclist was in the truck's blind spot. The driver physically couldn't see them." While commercial trucks do have massive blind spots (the "No-Zone"), this is not a legal excuse for running over a human being. Plaintiff attorneys defeat this defense by proving negligence in the cab:
Federal law requires commercial trucks to be equipped with specific hood-mounted convex mirrors (fender mirrors) designed explicitly to eliminate the right-side blind spot. If an attorney proves the driver failed to adjust these mirrors properly during their pre-trip inspection, or simply forgot to look at them before turning, the blind spot defense is destroyed.
If the truck passed the cyclist half a block before the intersection, the driver knew the cyclist was there. If the driver then slowed down and turned right, trapping the cyclist, they cannot claim the cyclist suddenly appeared in their blind spot. The driver negligently failed to track a vulnerable road user they had just overtaken.
Many fatalities occur when a cyclist is knocked off their bike and falls into the unprotected space between the truck's front and rear wheels. In some cities, commercial fleets are mandated to install "lateral protective devices" (side guards) to prevent cyclists from being swept under the wheels. Failure to equip the truck with these guards can establish corporate negligence.
The Importance of GoPro and Intersection Cameras
Because the cyclist is often severely injured and unable to give a statement to the police at the scene, the truck driver's version of events ("he darted out of nowhere") goes unchallenged on the initial police report. To reverse this, attorneys immediately subpoena city traffic cameras, transit bus dashcams, and the truck's own forward-facing camera to prove the cyclist was operating legally in their lane.
