Common mistakes on the theory test

Many fail the theory test because they make repeating mistakes that can easily be avoided with the right preparation. Here are the most common traps and how to steer clear of them.

The most common error categories

Sign confusion

Many candidates confuse danger sign with prohibition sign . Remember:

• Danger signs are triangular with a red frame and warnings of danger
• Prohibition signs are round with a red border and prohibit something
• Mandatory signs are round with a blue background and mandate something

Use sign memorization techniques to distinguish them clearly.

Giving way confusion

The most frequent mistake is about giving way. Candidates forget that:

• Sign overrides right-hand rule always
• In roundabout you have a duty to give way to traffic that is already in the ring
• In the event of exit from the right of way, you have a duty to give way to crossing traffic
• The right-hand rule only applies when there are no signs or other regulations

Errors with numbers and calculations

Questions about speed and distance require you to know the spells by heart. Common mistakes:

• Forgetting that the braking distance increases squarely – double speed gives four times the braking distance
• Mixes reaction time and reaction length – reaction length depends on speed
• Forgetting the three-second rule as a social distancing tool

How to avoid the mistakes

• Practice with mock exams under realistic conditions with a time limit
• Read the question twice before answering – many errors are due to rushed reading
• Learn the signs in groups instead of individually
• Repeat first aid regularly, especially the order CPR and stable lateral position
