Detailed Answer
To prove negligence in a collision at a traffic signal or exit under Washington law, you must establish the four elements of negligence: duty, breach, causation, and damages. Under Washington common law, every motorist owes a duty of care to other road users. A breach occurs if a driver violates traffic statutes or fails to act as a reasonable person would under similar circumstances.
Washington law requires motorists to obey traffic-control devices such as signals and signs. For example, RCW 46.61.055 (Failure to obey signal indicating stop) mandates that a driver stop at a steady red signal and only proceed when safe. RCW 46.52.020 (Duty to stop, give information, and report accidents) requires involved parties to report collisions and exchange information at the scene.
Key types of evidence include:
- Police or State Patrol reports. Official reports often include crash diagrams, witness statements, and officer observations.
- Photographs and videos. Capture signal light status, vehicle positions, skid marks, and road conditions immediately after the collision.
- Witness statements. Eyewitness accounts describing signal phases, vehicle speeds, and driver actions.
- Traffic-camera or surveillance footage. Intersection cameras may record signal timing and vehicle movements.
- Event data recorder (EDR) information. Vehicle “black boxes” log speed, braking, and steering inputs moments before impact.
- Expert analysis and reconstruction. Specialists use physics, measurements, and software to model the collision and determine fault.
By combining these evidence types with the legal standards in Washington statutes, you can build a solid case to prove another driver’s negligence.
Helpful Hints
- Collect evidence promptly. Traffic conditions and signals can change.
- Request the collision report early from the Washington State Patrol or local police.
- Preserve witness contact information—memories fade over time.
- Take multiple photos and videos from different angles.
- Consider hiring an accident reconstruction expert for complex cases.
- Keep all medical records and repair bills to document damages.
- Review the relevant statutes above to understand each party’s obligations.
