What is the difference between rear-end collision and vehicle rollback marks?

[MacThomas]

The difference between rear-end collision and vehicle rollback marks is that rear-end collision marks are uneven (one high and one low), while rollback marks are horizontal. Below is relevant information about common rear-end collisions: 1. Rear-end collision caused by the front vehicle reversing or rolling back: These two types of rear-end collisions frequently occur, usually at intersections while waiting for traffic signals. The front vehicle may not have engaged the foot brake, mistakenly shifted into reverse gear, or experienced rollback when starting on a slope. In both cases, the front vehicle bears full responsibility, provided the rear vehicle did not move before the collision occurred. 2. Sudden braking by the front vehicle: If the rear vehicle maintained a safe following distance, a rear-end collision would not occur. However, a complete determination requires reviewing the rear vehicle's dashcam footage. If the front vehicle intentionally braked suddenly, it may also share partial responsibility.
