Orange barrels on a highway

Use blue or white reflectors to mark driveway entrances


BEMIDJI, Minn. – Property owners are reminded to use only blue or white reflectors to mark driveway entrances. “Using other colors like red, orange or yellow can be dangerous for motorists, because it can appear as though they are approaching or following a vehicle,” said Tom Johnson, MnDOT permit office.

In addition to using blue or white reflective markers, property owners should use reflectors that are a minimum of three inches across and double sided. The reflectors should be located at least 12 feet from the outside edge of the shoulder and no more than five feet above the ground. Reflectors should be placed on their own structure, not on mailboxes or permanent posts.

In accordance with Minnesota Statute 169.07, MnDOT may remove existing reflectors if they obstruct or interfere with the effectiveness of any traffic control device.
