Which of the following vehicles is prohibited from using a motorway?

The prohibition of cyclists and pedestrians from using motorways is rooted in the safety regulations aimed at protecting vulnerable road users. Motorways are designed primarily for high-speed, long-distance travel, and feature specific requirements regarding vehicle types to ensure safety and efficiency. Cyclists and pedestrians, who are significantly more exposed to the risks of high-speed traffic, lack the necessary speed and protective design features of vehicles, making their presence on motorways both unsafe and impractical.

Buses over 24 seats, motorbikes over 50cc, and cars towing a trailer are all permitted on motorways under the appropriate conditions, as they are designed for higher speeds and can better manage the traffic flow expected on such roads. This distinction emphasizes the need for specific vehicle classifications to maintain safety standards on motorways.
