In my last post, I told you about a rule of the road concerning turning at an intersection (you must turn into the lane of travel closest to you). If you don’t follow this rule, law enforcement can pull you over. No one wants that! You need to also know Idaho’s “5-second rule”!


You must signal for a minimum of 5 seconds before changing lanes on highways in Idaho. The law, Idaho Code § 49-808(2) states: “A signal of intention to turn or move right or left when required shall be given continuously to warn other traffic. On controlled-access highways and before turning from a parked position, the signal shall be given continuously for not less than five (5) seconds and, in all other instances, for not less than the last one hundred (100) feet traveled by the vehicle before turning.”

There are several cases involving the “5-second rule” and all have held that a traffic stop based on a driver’s failure to adhere to this rule is sufficient and adequate cause for law enforcement to pull a driver in Idaho over. If you want to avoid an encounter with law enforcement, you must follow this rule as well.

Being pulled over for a traffic infraction takes up your valuable time and is stressful. Not only that, it opens up the possibility of police developing further evidence that could lead to your arrest for DUI. Follow the rules of the road; you cannot be pulled over if you do!
