Which of the following groups are prohibited from using motorways?

• A. Pedestrians, provisional licence holders, motorcycles under 50cc, cyclists, horse riders, and slow-moving vehicles.
• B. Only pedestrians are prohibited.
• C. Only cyclists are prohibited.
• D. Only horse riders are prohibited.

Answer: (A)

Motorways are built for high-speed, high-velocity traffic and have limited opportunities for slower or vulnerable road users. Allowing pedestrians, riders of slow or non-motorized vehicles, or learners with only a provisional license would create serious safety risks because these users cannot match the speed or recover quickly in the fast-flowing traffic.

Pedestrians on motorways would have no safe space or barriers to protect them from fast-moving vehicles. Provisional licence holders are not yet fully tested and typically lack the experience required for merging, overtaking, and reacting to high-speed traffic. Motorcycles under 50cc are too slow to safely blend with motorway speeds, potentially causing delays and hazards. Cyclists and horse riders are vulnerable and can be overwhelmed by the speed and volume of traffic. Slow-moving vehicles, such as tractors or other large, l ow-speed machinery, create dangerous delays and overtaking hazards on a road designed for fast traffic.

So, all those groups are prohibited from using motorways, making the listed option the best answer.
