When driving too quickly in wet conditions, your tires may lose all contact with the road surface. Loss of traction will cause the vehicle to ride on top of the water, which is called "hydroplaning." The best way to prevent this from happening is to drive more slowly in rainy or wet conditions than you would when driving during ideal weather conditions.

A flashing yellow traffic light means drivers must slow down, be more aware, and proceed with caution. Be alert to crossing traffic and pedestrians.

Slow-moving vehicles, such as farm tractors, road maintenance vehicles, and animal-drawn carts, display an orange and red triangle on the back.

Anytime you want to merge with other drivers, you need to find a gap large enough for you to safely enter into the flow of traffic. You should not stop on the entrance ramp to an interstate highway unless there are no gaps into which you may safely merge.

A round sign always indicates that you are approaching a railroad crossing.

Use low beam headlights when driving in fog, rain, or snow. High beams may reflect off of the weather and make visibility even poorer.

Drive according to the posted maximum speed limit. You may drive more slowly than the posted speed limit, based on road conditions, but it is illegal to drive any faster than the posted speed limit.

The posted maximum speed limit is the fastest legal speed you can travel on a road under ideal conditions. It is safest to drive at the same speed as surrounding traffic, up to the maximum speed limit. Maintaining a safe speed at all times is a responsibility shared by all motorists.
