Your learner might have trouble adapting to the pressures of driving at high speeds. Here are some tips you can pass on to calm their nerves.
The 2-second rule is vitally important at higher speeds. Higher speed means things happen faster. Decisions have to happen early and quickly.
There is not much room for error, so leaving a reasonable following distance is important.
Get your learner to practise the 2-second rule at higher speeds. It works exactly the same - pick a landmark up ahead, and start counting when the vehicle in front of you passes it. You should get to a count of 2 before you pass the landmark yourself.
Talk to your learner about the need to steer gently with no sudden movements. Holding a centred position in the lane is important—learners tend to drift across.
Look ahead for information signs on road conditions.
Look for brake lights (stop lights) not just in the car directly in front, but 2-3 cars ahead.
Watch out for slower drivers on the motorway or in heavy traffic as this can create a hazard.
Remind your learner that it's important to always drive at a speed that's appropriate for the conditions. 100 km/h is a maximum, not a goal to aim for regardless of the conditions.
In general, your learner should keep in the left lane unless they are overtaking.
Encourage them not to worry about impatient drivers. If someone is tail-gating them, that person can use the right lane to pass. If you're already in the right lane and someone is tail-gating encourage your learner to signal left and pull over to the left lane to let them pass as soon as they can find a safe gap.
