If you miss your exit on the freeway, you should not:

If you miss your turn or exit, do not back up in the travel lane or on the shoulder. Continue to drive to the next exit or crossroad. Drivers do not expect a vehicle to be backing toward them on the roadway and doing so will likely cause a collision.

• Continue on the freeway and find an alternate route to your destination.
• Proceed to the next exit, leave the freeway, and return to your proper exit.
• Back up on the road or shoulder.
