Roundabouts are popping up everywhere and most Minnesota drivers are still getting use to them. The question of whether or not to use your turn signal at a roundabout comes up a lot. Here's what Minnesota State Patrol Sgt. Troy Christianson said: 

"Minnesota state law says that a signal of intention to turn right or left shall be given continuously during not less than the last 100 feet traveled by the vehicle before turning. A person whose vehicle is exiting a roundabout is exempt from this subdivision. So per state law, a signal is not required once in a roundabout. Entering a roundabout requires a signal." 

Christianson went on to explain, "roundabouts produce better traffic flow, making the intersection safer. Roundabouts show an 89 percent decrease in fatal crashes, a 74 percent decrease in life-altering injury crashes and a 39 percent decrease in all crashes. They also handle high levels of traffic with less delay than most stop signs or signals."

You can avoid a ticket — and a crash — if you simply buckle up, drive at safe speeds, pay attention and always drive sober.  Help us drive Minnesota Toward Zero Deaths.
