Question

Difficulty: Very hardOvertaking Rules

If the solid white line of a double white line system is on your side of the road, you may cross it to overtake an agricultural tractor, provided the tractor is travelling at 10 mph (16 km/h) or less and it is safe to do so.

Answer: Answer

Answer

False
The statement is false because the legal exception allowing drivers to cross a solid white line to overtake applies strictly to pedal cycles, horses, and road maintenance vehicles travelling at 10 mph or less. Agricultural tractors are excluded from this exception, making it a traffic offence to cross a solid white line to pass them.

Step-by-Step Solution

1
Identify the primary rule regarding double white lines with a solid line on your side.
You must not cross or straddle the solid white line unless specific exceptions apply.
This is a mandatory safety rule under the Highway Code to prevent head-on collisions in restricted visibility areas.
2
Recall the exact legal exceptions for overtaking across a solid white line.
You may cross the line only to pass a stationary vehicle, or to overtake a pedal cycle, a horse, or a road maintenance vehicle travelling at 10 mph (16 km/h) or less.
The law defines a highly restricted list of road users to minimize the time a driver spends on the wrong side of the road.
3
Evaluate the agricultural tractor against the legal exceptions.
An agricultural tractor is not a pedal cycle, a horse, or a road maintenance vehicle.
Because tractors are not on the explicit list of exceptions, crossing the solid line to overtake one is illegal, regardless of how slowly it is moving.
