Why can't I park on double white lines?
Rule 240 of the Highway Code prohibits the stopping or parking of a vehicle (or trailer) under a number of specified circumstances, which include:
- a road marked with double white lines, even when a broken white line is on your side of the road, except to pick up or set down passengers, or to load or unload goods.
This rule is intended to promote road safety. The double white line system is painted with the purpose of warning drivers of the presence of a hazard. Parking adjacent to these lines presents another hazard by:
- forcing a pedestrian to walk in the road;
- causing a car driver/passenger to exit their vehicle so to enter the road;
- causing a vehicle using that road to straddle/cross the solid white line and bringing them in to conflict with opposing traffic.
- causing vehicles to overtake pedestrians/horse riders/cyclists too close in an attempt to avoid crossing/straddling the solid white lines.

What is a double white line?
Double white lines are used to inform drivers of a hazard.
They can appear in a number of ways:
- where the line nearest to you is broken;
- where the line nearest to you is solid; and,
- where both lines are solid.
Double white lines where the nearest line is broken
Rule 128 of the Highway Code says you may cross the lines to overtake if it is safe and if you can complete the manoeuvre before reaching a solid white line on your side.
Double white lines where the nearest line is solid
Rule 129 of the Highway Code says you must not cross or straddle these lines unless it is safe and you need to do so in order to enter adjoining premises or a side road.
“You may cross the line if necessary, provided the road is clear, to pass a stationary vehicle, or overtake a pedal cycle, horse or road maintenance vehicle, if they are travelling at 10 mph (16 km/h) or less.” (Note however the section below “Am I allowed to cross a double solid white line?”)
Double white lines where both are solid
As per rule 129. These are used to prohibit drivers from travelling in an area of the road used by the opposing flow of traffic, generally because overtaking visibility is restricted and would be dangerous.
Is Rule 240 of the Highway Code enforceable?
Section 22 Road Traffic Act 1988 makes it an offence for the person in charge to leave a vehicle or trailer on a road in such a position or condition as to cause a danger to other road users.
