Making a U-turnYou are normally allowed to make U-turns, as long as the road is clear in both directions and it is safe to do so. Make sure you have enough room to complete the turn and don't create a hazard for oncoming vehicles.
You aren't allowed to make U-turns if a 'No U-turn' sign is displayed.
Making a turn over a no-passing lineYou can cross over the solid yellow no-passing line (if it is safe to do so) when making a turn to enter a driveway or side road.
However, bear in mind that no-passing lines are often marked where visibility is limited, so special care is required. It may be safer to turn further along the road, where visibility is better. See Passing for more information about no-passing lines.
No-passing lineOn some sections of road there will be a solid yellow line painted on your side of the centre line. This line is called a no-passing line.
No-passing lines are usually there because it's unsafe to cross the centre line to pass, because features like hills and curves make it impossible to see if there is oncoming traffic.
Sometimes no-passing lines are marked because: - there is already a passing lane on your side of the road and you must use that to pass
- the road is multi-laned, so you do not need to cross the no-passing line to pass.
You must not pass another vehicle if it means you have to cross over a no-passing line on your side of the centre line.
