Dip Signs are MUTCD Compliant (MUTCD W8-2) and indicate that there are upcoming low spaces in the road to watch out for. Dip Signs are useful devices to help display official regulations and provide mandatory information to drivers and pedestrians on both private and public roadways.
Compliance
Section 2C.28 BUMP and DIP Signs
Guidance
BUMP (W8-1) and DIP (W8-2) signs should be used to give warning of a sharp rise or depression in the profile of the road.
Option
These signs may be supplemented with an Advisory Speed plaque.
Standard
The DIP sign shall not be used at a short stretch of depressed alignment that might momentarily hide a vehicle.
Guidance
A short stretch of depressed alignment that might momentarily hide a vehicle should be treated as a no-passing zone when center line striping is provided on a two-lane or three-lane road.
