Speed Limits and Controls
- 1/10When driving in a school zone, drivers must
Michigan school zones require drivers to slow down to 25 MPH for children’s safety. This helps reduce injury risk and allows time to react to unexpected movements.
When driving in a municipal, business, or residential areas, speed should
These areas have frequent stops, crosswalks, and pedestrian activity. A 15 MPH speed helps drivers maintain control and react safely to potential hazards.
When driving on streets and highways without special signage, the default limit is
Drivers should know that 55 MPH is the default for most roads in Michigan unless signs indicate otherwise. Adjust this speed for traffic or road conditions.
If traveling on limited access highways in Michigan, the speed limit is
Limited access roads allow for higher speeds due to fewer intersections and controlled access. However, always drive slower if conditions demand it.
When the posted highway speed limit is 70 MPH, drivers must still
Michigan law requires that drivers keep up with the flow of traffic. Driving too slowly on a high-speed road can be as dangerous as speeding.
Driving too slowly is illegal if it blocks or delays
You must not drive so slowly that you obstruct safe, normal-speed traffic. Keep right and let faster vehicles pass if youre moving slower than others.
When driving slower than other vehicles, you must
This allows other vehicles to pass safely on the left, reducing congestion and improving highway safety.
Impact of following the speed limit
Staying within the speed limit allows more time to react to hazards and lessens the force of a collision, helping to keep you and others safe on the road.
If you double your speed, your vehicle’s impact
Speed greatly multiplies crash force. For example, hitting something at 60 MPH is four times more forceful than at 30 MPH, making crashes more severe.
Increasing speed threefold results in
The impact force in a crash increases dramatically with higher speeds. Excessive speeding significantly raises the chances of severe injuries and extensive vehicle damage during a collision.
