Prohibition signs
What do prohibition signs look like?
Prohibition signs are round with a white background, red border and black symbols. There are exceptions to this rule of thumb. Prohibition signs forbid traffic of certain vehicles or specific manners of driving. The signs typically apply from the sign until the next intersection.
No overtaking by trucks
The prohibition applies to trucks with a maximum permitted weight over 3,500 kg overtaking motor vehicles with more than two wheels. The prohibition does not apply to overtaking that, under the traffic rules, may lawfully take place on the right. The prohibition applies up to sign 337 "End of no overtaking by trucks," or over a distance specified by a supplementary sign.
