Intersection Accidents: How Fault and Liability Are Determined

Intersections are among the most common locations for serious car accidents, largely because they involve multiple vehicles crossing paths, turning, and making split-second decisions about right-of-way. When a collision happens at an intersection, determining fault often comes down to carefully reconstructing exactly what happened in the seconds before impact, since more than one driver can share responsibility for the same crash.

Traffic Signals and Right-of-Way Rules

Right-of-way rules form the backbone of intersection fault analysis. A driver who runs a red light, fails to yield when required, or turns left across oncoming traffic without a safe gap is typically found at fault for a resulting collision. Even at intersections without traffic signals, established right-of-way rules, such as yielding to the vehicle that arrived first at a four-way stop, determine which driver had the legal right to proceed.

How the California Vehicle Code Applies

California's Vehicle Code lays out specific rules governing right-of-way, permitted turns, and driver responsibilities at intersections, and violations of these rules are frequently cited as evidence of negligence in a resulting injury claim. For example, a driver making a left turn is generally required to yield to oncoming traffic unless protected by a green arrow, and a driver approaching a stop sign must come to a complete stop and yield to cross traffic and pedestrians already in the intersection.

Comparative Negligence in Intersection Cases

Intersection accidents frequently involve shared fault, since one driver might have been speeding while another failed to yield properly. California follows a pure comparative negligence system, meaning an injured driver can still recover compensation even if they were partially at fault, though their recovery is reduced by their percentage of responsibility. This makes a careful, evidence-based fault analysis especially important in intersection cases, where insurers often try to assign a larger share of blame to the injured party.

Evidence That Helps Establish Fault

• Red light camera or intersection surveillance footage
• Police accident reports and officer observations
• Witness statements from drivers, passengers, or pedestrians
• Vehicle damage patterns consistent with a specific point of impact
• Traffic signal timing records

Common Intersection Accident Scenarios

• T-bone or broadside collisions, where one vehicle strikes the side of another
• Left-turn accidents, where a turning driver misjudges an oncoming vehicle's speed or distance
• Red-light and stop-sign violations, where one driver disregards a required stop
• Four-way stop disputes over which vehicle arrived, or should have proceeded, first
• Pedestrian and cyclist collisions within a marked or unmarked crosswalk

Left-Turn Accidents and the Unprotected Left

Left-turn collisions are among the most common types of intersection crashes, particularly at intersections where a left turn isn't protected by its own green arrow. A driver turning left is generally required to yield to oncoming traffic and wait for a safe gap before proceeding, and misjudging the speed or distance of an oncoming vehicle is one of the most frequent causes of these crashes. Because the turning driver typically has an obligation to yield, they're often found at fault, though exceptions exist, including when the oncoming driver was traveling well above the speed limit or ran a red light after the turning driver had already begun a reasonably safe turn.

Pedestrians and Cyclists at Intersections

Pedestrians and cyclists face particular danger at intersections, where turning vehicles and crossing traffic create multiple points of potential conflict. Pedestrians in a marked or unmarked crosswalk generally have the right-of-way over turning vehicles, and drivers are required to yield accordingly, but comparative negligence can still apply if a pedestrian crossed against a signal or stepped into traffic unexpectedly. Cyclists are generally entitled to the same right-of-way protections as vehicles when lawfully positioned in a lane or bike lane, and a driver who fails to check for a cyclist before turning can be found liable for a resulting collision.

Why T-Bone Collisions Cause Serious Injuries

Broadside, or T-bone, collisions are especially common at intersections and tend to cause more severe injuries than a typical rear-end crash, since a vehicle's side offers far less structural protection and crumple zone than its front or rear. Occupants on the side of impact frequently suffer traumatic brain injuries, chest and abdominal trauma, and pelvic or hip fractures, even in crashes that occur at relatively moderate speeds. Because of this, claims arising from T-bone intersection crashes often involve significant medical damages that go well beyond what the visible vehicle damage might initially suggest.

Choosing an Attorney for a Disputed Intersection Case

Intersection accidents are disputed more often than many other crash types, since both drivers frequently believe they had the right-of-way. An attorney who knows how to obtain and analyze red light camera or nearby business surveillance footage, request traffic signal timing data, and work with accident reconstruction experts when needed is better positioned to overcome a contested liability dispute than one who relies primarily on the police report alone.

Because intersection accidents so often involve competing accounts of who had the right-of-way, building a claim on solid evidence rather than assumptions is essential. Gathering documentation quickly, before footage is deleted and memories fade, gives injured drivers the strongest possible position when fault is disputed.
