In Michigan people on bikes are required to follow the same laws as other drivers.
Here are a few key principles that underpin all traffic laws:
First Come, First Served
Everyone on the road is entitled to the lane width they need. This includes the space behind, to each side and the space in front. If you want to use someone else’s space you must yield to whoever is using it.
Ride on the Right
Everyone must drive on the right-hand side of the roadway.
Yielding to Crossing Traffic
When you come to an intersection, if you don’t have the right of way, you must yield.
Yielding when Changing Lanes
If you want to change lanes, you must yield to traffic that is in your new lane of travel.
The slowest vehicles on the road should be the furthest to the right. Where you position yourself on the road depends on the location of any parked cars, your speed, and your destination. Always pass on the left.
Bikes can share the same lane with other drivers. If a lane is wide enough to share with another vehicle (about 14 feet), ride three feet or so to the right of traffic to avoid the gutter pan. If the lane is not wide enough to share, “take the lane” by riding in the middle.
When there is a lane that is used for more than one direction, use the rightmost lane going in the direction you are traveling.
Follow all street signs, signals, and markings
Bicyclists are required to follow all traffic control devices, just as drivers do, including traffic lights and signs.
