Are you allowed to drive a bus with a single axle load of 10 tons on a road marked in such a way?
Show the correct answer
Correct answer
YES
Explanation
In the photo you can see a road outside a built-up area, and next to it two red boards with white numbers "14" and "2" - these are signs E-15a "national road number with a permitted axle load of up to 11.5 t". You are allowed to drive a bus with a single axle load of 10 tonnes here - the answer is YES.
The Regulation on road signs and signals states that sign E-15a marks a national road on which vehicles with a single axle load not exceeding 11.5 t may travel. A bus with an axle load of 10 t is well within this limit. The type of sign matters here: E-15a means 11.5 t, while, for example, sign E-15b with a regional road number means only 8 t - then the answer would be different. Axle load is the part of the vehicle's mass that presses on the road surface through the wheels of one axle, so exceeding the limit quickly damages the road. Also watch out for signs B-19 "no entry for vehicles with an axle load of more than ... t", which may limit axle load on individual sections, for example before a bridge.
Legal basis: § 65 para. 1 point 1 and para. 2 point 1 of the Regulation on road signs and signals
