The B17 sign prohibits traffic from proceeding if there isn't an indicated minimum distance maintained between vehicles. This generally means you cannot enter the area or continue driving if you are following another vehicle too closely.
Upon seeing the B17 sign, you must assess the distance between vehicles. If the distance is less than what is indicated (often by a supplementary plate), or if you are too close to the vehicle in front, you must not enter the controlled zone or continue driving. If necessary, choose an alternative legal route.
The B17 sign itself doesn't typically have general exceptions, but supplementary plates can significantly limit its application. These plates might specify certain vehicle types, times of day, or specific distances. Always read these plates carefully before deciding to proceed.
A common trap is assuming the restriction doesn't apply to you or simply following another driver through the area, thinking it's permitted. Another is not noticing or understanding a supplementary plate that modifies the rule. Remember, the responsibility lies with you to comply with the sign and any associated plates.
The prohibition indicated by the B17 sign typically ends when you see an end-of-restriction sign, or when the road layout or signage clearly indicates the end of the controlled zone. Simply because other drivers ignore the sign does not mean the restriction is lifted for you.
