Traffic usually travels faster on dual carriageways and on some rural roads than on ordinary roads and you will need to assess traffic situations more quickly. Using your mirror and concentrating all the time are even more important where traffic is faster.

In good visibility and weather conditions, drive at a steady cruising speed within the limits of the vehicle. You must not break the speed limit for the road or for your vehicle. On wet roads, or in fog or high winds, keep your speed down.

Looking well ahead will give you more information as well as more time to react to it.

Do not walk on the carriage-way. In an emergency be particularly careful to keep children and animals off the carriageway including the hard shoulder.

Regulatory signs showing the maximum speed limit for the road

The speed limit on normal roads is 50 km/h. On roads with faster traffic the speed limit may be either 70 km/h, 80 km/h or 100 km/h. 'Speed limit' signs will mark the beginning of a higher speed limit and will be repeated along the road. A '50 km/h speed limit' sign will mark the end of the higher speed limit.

When leaving a road with faster traffic adjust your driving to suit the new conditions. Your speed will be higher than you think - 70 km/h may feel like 50 km/h - so be sure to check your speedometer.

Keeping your distance from the vehicle in front is important if you are to allow yourself time to react if the unexpected happens or in an emergency. You may not be able to move to another lane to avoid the vehicle in front if it slows down or stops.

Use the 'Two-second' rule - leave a two-second time gap between you and the vehicle in front.

( See page 47 for more on the & 'Two-second&' rule.)

The 'reduce speed now' plate used with some warning signs on roads with faster traffic.

You will need to slow down to a slow speed, or a speed slower than normal, to drive safely through the hazard ahead.
