B-5 No lorries

What it means

Bans lorries with a maximum permitted mass over 3.5 t, as well as tractor units, special vehicles over 3.5 t, agricultural tractors and slow vehicles. A number on the sign changes the mass threshold from which the ban applies.

In the exam

You can drive a car past B-5. If the sign shows e.g. "7 t", the ban applies only to lorries above that mass.

Legal basis: § 18 of the regulation of the Ministers of Infrastructure and of the Interior and Administration on road signs and signals (Dz.U. 2019 poz. 2310, as amended).
