Worked examples: how to reason through DTT questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: What does the power steering warning light indicate?

1. The power steering system has a fault — steering will be heavier and more difficult
2. Steering fluid is at the correct level
3. Sport steering mode is active
4. The wheel alignment needs checking

Answer: A. The power steering system has a fault — steering will be heavier and more difficult

Explanation:

The correct answer is that the power steering system has a fault and steering will be heavier. This warning light tells you the assistance that makes the wheel easy to turn may be reduced or lost. The car can usually still be steered, but it takes much more effort, especially at low speed and when parking.

The other options are wrong for these reasons. A correct fluid level would not trigger a warning light. A sport steering mode is a driver setting, not a fault warning. Wheel alignment problems show up as pulling or uneven tyre wear, not as this light.

Rule to remember: a steering warning light means a fault. Slow down, expect heavy steering and have the car checked.

Example 2

Question: A red and white striped pole at a pedestrian crossing is called:

1. A Belisha beacon
2. A bollard
3. A refuge post
4. A signal repeater

Answer: A. A Belisha beacon

Explanation:

The correct answer is a Belisha beacon. The name belongs to the flashing amber globe on a striped pole that marks a pedestrian crossing. Learn the name together with the picture, because the test can ask either way. Note that our question describes the pole's stripes loosely, so focus on the term itself.

A bollard is a short post used to block or guide traffic. A refuge post marks a safe island in the road. A signal repeater is a vehicle indicator or a repeated signal, not a crossing marker.

Rule to remember: when you see the beacon, expect pedestrians and be ready to slow down and stop for anyone on the crossing.

Example 3

Question: What does a green traffic light mean?

1. You may proceed if it is safe to do so
2. You have absolute right of way and must proceed
3. Pedestrians may not cross
4. Speed up to clear the junction

Answer: A. You may proceed if it is safe to do so

Explanation:

The correct answer is that you may proceed if it is safe to do so. A green light gives you permission to go, not an automatic right of way. Other vehicles may still be clearing the junction, and pedestrians may still be crossing.

The claim of an absolute right of way is wrong because you must still check the junction. The claim that pedestrians may not cross is wrong because people already on a crossing, or those with their own signal, may still be there. Speeding up to clear the junction is wrong because it adds risk and encourages rushed decisions.

Rule to remember: green means go only when the way ahead is clear and safe.

How to use these practice tests

Start by reading the official RSA material so you know the rules the questions are based on. Then take the main free practice test to see where you stand without any preparation. Do not worry about the score at this stage. Its purpose is to show you which topics need work.

Next, work through the topic sets that match your weak spots. Road signs, give way rules and junctions, and speed and stopping distances are common trouble areas for new candidates. For every wrong answer, read the explanation and write down the rule in your own words. Retake that set a few days later to check that the rule has stuck.

Hazard awareness and risk perception sets are worth practising separately, because they train a different skill from recalling rules. Spend time on how you spot developing danger, not just on what the correct answer is.

In the final days, run the main practice test under timed conditions, keeping to the 45-minute limit and aiming for 35 correct out of 40. Our questions are written by us and are not real exam questions, so use them to build understanding, not to predict what you will see.
