Most riders already ride defensively, but certain motorcycle crash causes keep showing up in serious cases. Understanding how these collisions happen—and what proof establishes fault—can make the difference in a claim.

Unsafe Left Turns at Intersections

Left-turn crashes happen when a driver turns across the rider’s path, often misjudging speed or failing to yield. These are among the most common severe collisions for motorcyclists. Look for:

• Signal timing and turn arrows from traffic data or city logs.
• Dashcam, traffic camera, or storefront surveillance.
• Skid marks and impact points establishing your right of way.

Road-safety overviews from NHTSA help show typical patterns at intersections.

Speeding & Following Too Closely

Excess speed and tailgating reduce a driver’s time to react to a rider’s lane position or braking. Evidence may include EDR (“black box”) data, phone telemetry, or reconstruction showing stopping distances.

Visibility & Lane Encroachment

Drivers who change lanes without checking blind spots or who “drift” into a lane can sideswipe a rider. Classic clues include mirror settings, lane position photos, and scrape patterns along vehicle flanks. Visibility problems are a central theme in many motorcycle crash causes.

Impairment & Distraction

Alcohol, drugs, fatigue, and phone use slow reaction time and attention. Useful evidence:

• Police tests and field sobriety notes; bar receipts when relevant.
• Cell records and app activity logs indicating texting or streaming.
• Work or shift logs documenting fatigue windows.

For context on distracted driving risks, see IIHS research.

Road Hazards & Infrastructure

Potholes, gravel, metal plates, and poor drainage can cause sudden loss of traction. Photos with scale (coin/ruler), 311 or municipal reports, and witness statements help prove dangerous conditions. Some cases involve government notice and timelines for repair.

Evidence That Wins Motorcycle Cases

• Scene capture: photos/video of lanes, traffic controls, debris fields.
• Vehicles: preserve the bike and the other vehicle for inspection.
• Witnesses: names, numbers, and quick recorded statements.
• Medical records: immediate care ties injuries to the crash and documents causation.
