Gas service sign

What does it mean?

The fuel-pump symbol on a blue sign points drivers toward gasoline service. Read the rest of the sign assembly to locate the exit, turn or distance associated with that service.

What to do when you see it

  1. Check the direction information before changing lanes.
  2. Take the indicated exit or turn using normal traffic rules.
  3. If you miss the turn, continue to another safe legal route.

How to recognize it

  • White fuel pump with a hose.
  • Blue square background and white border.

On the road

Your fuel gauge is low and you see a blue pump symbol beside an exit direction. Move into the exit lane when it is safe and follow the service signs.

Don’t confuse it with

Red-white-blue Interstate highway shield with number 79.

Interstate Route sign

A route shield identifies a highway, while the blue pump identifies a service available along the route.
