When you speed, you lose the ability to control your vehicle quickly in emergencies. It is harder to stop or turn safely, making crashes more likely and more dangerous.

Even if the posted speed is 55 mph, it might not be safe in rain or snow. Smart drivers adjust their speed based on visibility, road grip, and traffic flow.

The law requires that you drive at a reasonable and prudent speed, especially in bad weather. That means slowing down even if you are technically under the limit.

Wet, icy, or loose gravel surfaces reduce traction. Driving too fast on such roads makes it easy to skid, so you are expected to slow down significantly.

You must always be able to stop safely within the distance you can see ahead. If you are driving faster than your visibility allows, you are violating this rule.

If you are driving 30 mph or more at night, your headlights must light up at least 200 feet ahead. It helps ensure you can see and react fast enough.

Holding up traffic by driving too slowly is dangerous. If you are delaying vehicles behind you and it is not due to weather or emergencies, you can be cited.

Reckless driving means showing a willful disregard for safety. That can include extreme speeding, weaving through traffic, or ignoring road signs.

On multi-lane roads, slower traffic should always stay in the right lane. This helps traffic flow more smoothly and prevents unnecessary lane changes.

Roundabouts are not for speeding through. Designed for low-speed travel, they require slowing to about 15-20 mph for safe navigation and yielding.

Do not rush into a roundabout. Instead, ease off the gas and yield to vehicles already circulating inside it keeps traffic flowing and avoids crashes.

If you slow down from 70 mph to 60 mph during your commute, you could save about 1.3 gallons of fuel every workweek. Over time, that adds up.
