CDifficulty 2/5

An ordinary 5,000 kg MAM lorry travels on an interurban dual carriageway with no reason justifying travel below the minimum. Below what speed would it breach the general minimum-speed rule?

Correct answer

60 kilometres per hour.

60 km/h. This general minimum applies to motor vehicles on motorways and dual carriageways, even without other traffic. It does not require maintaining 60 when traffic, road or vehicle conditions prevent doing so safely. Specific cases also exist for special vehicles or transport and escort duties. Adapt speed to conditions and obey applicable limits; needing to go more slowly in congestion does not itself breach the rule.
