Driving too fast above the speed limit or too slow below the speed limit are common factors that lead to collisions.

The driver should be careful to note and stick to the posted speed limit in the area.

When overspeeding, the driver's stopping distance significantly increases. As a result, even if they spot a risk on the road, the driver may not be able to stop in time.

Going too slow can be dangerous as the driver will hold up traffic. The chances of getting rear-ended are significantly higher when driving too slow. They can be fined for either moving too slowly or too fast.
