ATTT Driving Theory common mistakes
ATTT Driving Theory · Understand the traps and how to avoid them.
Treating a round sign with a red border as a prohibition only when it contains a car or a number, and reading it as a warning when it shows a symbol such as a bicycle or a pedestrian.
Candidates memorise a handful of common signs by picture and never learn the shape-and-colour grammar of the sign system, so unfamiliar symbols get guessed from the icon rather than the frame.
What to do instead
Before revising individual signs, learn the frame rules: red-bordered circles are prohibitions, red-bordered triangles are warnings, blue circles are mandatory instructions, blue rectangles are information. Then sort a set of 40 signs by frame first, symbol second, and check yourself on signs you have never seen in the handbook.
Answering right-of-way questions by who arrived first, even when the other vehicle is on the right at an unmarked intersection or is already circulating in a roundabout.
Everyday driving habits and courtesy conventions feel like rules, and the priority order (signs and signals, then the give-way-to-the-right default, then turning across oncoming traffic) is rarely rehearsed as an explicit hierarchy.
What to do instead
Write out the priority ladder on one page and apply it aloud to ten junction scenarios: signal, then sign, then road marking, then the default rule. Drill the two exceptions that override habit, namely yield to traffic already on the roundabout and yield when turning left across oncoming traffic.
Reading a hazard-perception clip as a single event and answering about the most dramatic moment rather than the first moment a hazard becomes visible and requires a response.
Candidates watch passively like a passenger and react to the obvious climax, missing the early cues such as a brake light two cars ahead, a pedestrian at a kerb or a ball rolling into the road.
What to do instead
Practise the scan pattern explicitly: mirror, ahead, kerb, mirror. On each clip, pause at the first frame where a hazard could be detected and say what you saw. Train yourself to answer with the earliest defensible moment, not the latest.
Choosing the highest permitted speed as the correct answer whenever a limit sign is shown, ignoring the road, weather and visibility conditions in the scenario.
Speed-limit questions train a simple number-matching reflex, and candidates conflate the legal maximum with a safe speed.
What to do instead
For every speed question, state the limit and then state the safe speed separately, and justify the second with the visible conditions. Learn the standard reductions for rain, fog, night and roadworks, and remember that the limit is a ceiling, not a target.
Confusing solid and broken line meanings, treating a solid centre line as merely advisory and a broken line as a no-overtaking barrier.
Line markings are learned visually from a diagram without the underlying logic that solid means do not cross and broken means may cross if safe, so the two get swapped under exam pressure.
What to do instead
Learn the principle: a continuous line is a prohibition, a broken line is a permission subject to safety. Then work through paired examples, including double lines where the nearer line governs, and describe each one in words before looking at the answer.
Giving first-aid answers that prioritise moving the casualty to comfort or removing a helmet or clothing, instead of securing the scene and calling emergency services.
Candidates answer from instinct and film-derived imagery rather than the accepted order of actions, and they underestimate the danger of moving a person with a possible spinal injury.
What to do instead
Memorise the fixed sequence: protect the scene and yourself, check responsiveness and breathing, call emergency services, then treat. Learn the specific prohibitions, namely do not remove a motorcycle helmet, do not move a suspected spinal casualty unless there is immediate danger, and do not give food or drink.
Mixing up braking distance, stopping distance and thinking distance, and answering a two-second-rule question with a distance in metres.
The three terms sound interchangeable and the underlying relationship, stopping distance equals thinking distance plus braking distance, is never written out, so recall collapses in the exam.
What to do instead
Draw the stopping-distance bar split into thinking and braking portions and label what changes each one: reaction time and speed for thinking, speed squared, tyres and surface for braking. Then practise converting the two-second rule into a distance at 50, 90 and 130 km/h.
Answering penalty and documentation questions with the severity of the outcome rather than the specific rule, for example assuming any collision automatically means licence withdrawal.
Candidates generalise from stories and news rather than learning the actual penalty structure, and they confuse administrative measures such as points, fines and suspension with criminal outcomes.
What to do instead
Build a one-page table of the offences you are most likely to be asked about, with the penalty, the number of points and any licence consequence in separate columns. Test yourself by covering one column at a time, and separate administrative penalties from criminal ones explicitly.
Checking only the mirror before changing lane or opening a door, without a shoulder check, and answering that mirrors give full rear visibility.
Mirrors are taught as the primary observation tool, and the blind spot is understood as a concept but not as a physical zone that must be checked by turning the head.
What to do instead
Adopt the routine mirror, signal, shoulder check, manoeuvre and repeat it in every hazard clip. Learn where the blind spots sit relative to the driver's seat, and apply the same discipline to the door-opening check for cyclists when parked.
Treating vehicle-safety items such as tyre tread, warning lights and load security as maintenance trivia and guessing the answer from the most technical-sounding option.
Mechanical content is studied last and memorised as isolated numbers without understanding why the limit exists, so the reasoning that would eliminate wrong answers is missing.
What to do instead
Learn each item with its purpose attached: tread depth for water displacement, tyre pressure for contact patch and heat, warning lights for what system is affected and whether driving is permitted. Link every number to the consequence of exceeding it, and revise this domain in short repeated sessions rather than one block.
