Crossing / Joining a Dual Carraigeway

When you wish to cross a dual carriageway or join it by turning right, treat each half as a separate one-way road. Cross the first half when it is clear and wait in the median space until there is a safe gap in traffic in the second half before you complete your crossing or turn. If the median is already blocked by another vehicle, WAIT until there is sufficient space available to enable you to clear the first half of the dual carriageway without stopping.

If the median is too narrow to accommodate your vehicle, wait on the side road until you can clear both carriageways at once. Always exercise special care in proximity to large vehicles or vehicles towing trailers when they are turning. Remember a long vehicle or combination needs additional room to negotiate a turn, since the rear wheels perform a shorter track than the front wheels.

Cyclists, motorcyclists and pedestrians in particular should be extra careful when in proximity to these vehicles.

Driving on Dual Carraigeways

On dual carriageways the general rule of driving on the left applies. The outer lane of a two-lane dual carriageway should be used only by -
• Faster moving traffic
• For overtaking
• When intending to turn right a short distance ahead.

The outer lane of a three-lane dual carriageway should only be used for overtaking or when it is intended to make a right turn a short distance ahead.
