Minnesota law allows motorists to make a right turn on red after coming to a complete stop, unless there's a sign indicating the turn is not allowed.
But Drive reader Mark wanted to know if the same rules apply when the right turn lane is separated from through traffic by an island, such as at the top of freeway entrance and exit ramps.
"Do you need to come to a complete stop if through traffic has a red light, or do you only need to yield to cross traffic?" he asked in an e-mail.
Anytime a driver encounters a red light, the motorist turning right should make a complete stop, check for traffic and make sure the coast is clear before proceeding, said Pete Hosmer, owner of A+ Driving School in White Bear Lake.
That's what drivers turning right from eastbound Bass Lake Road to southbound Bottineau Boulevard in Crystal are supposed to do. The right turn lane is separated from through traffic by a concrete divider and has a stoplight controlling traffic flow, including right turns. When the light is red, drivers must stop behind the white line and wait for a green light or until there is a safe opportunity to make the turn.
"Be sure to watch for oncoming cars making left turns in front of you," the Minnesota Driver's Manual says. "Sometimes oncoming traffic will have a green arrow before your light turns green."
Things are different at the signalized intersection of Lexington Avenue and Yankee Doodle Road in Eagan, where drivers turning right don't actually encounter a red light. Instead, signs instruct motorists making right turns to yield — meaning, slow down before merging onto the road and be prepared to stop for pedestrians, bicyclists and vehicles that have the right-of way. Turns can be made when there is a break in traffic.
The rules are less clear when right turn lanes are separated from through traffic but not controlled with a stoplight or yield sign.
