The minimum speed limit on motorways is the lowest speed you should drive to avoid creating danger for faster traffic. Driving too slowly on a motorway can be risky because it forces other drivers to brake or change lanes suddenly.
What “minimum speed limit” means
- It is a minimum safe speed requirement for that road section.
- It helps prevent slow vehicles from causing sudden traffic disruption.
- It may be shown on signs in some areas (depending on rules and road authority).
Why driving too slow can be dangerous
- It increases rear-end collision risk.
- It causes dangerous overtaking and weaving.
- It reduces traffic flow and creates confusion.
Safe approach
- Drive at a reasonable speed that matches traffic flow (without exceeding the maximum).
- Keep left and allow faster vehicles to pass.
- If your vehicle cannot maintain safe motorway speed, avoid the motorway or exit safely.
Tip: On motorways, being too slow can be as risky as being too fast.
Key Points
- Minimum speed limit is the lowest safe speed for motorway driving.
- Driving too slow can cause sudden braking and dangerous lane changes.
- Keep left and match safe traffic flow without exceeding the maximum.
- If your vehicle cannot maintain safe speed, exit safely.
