Denmark B Theory common mistakes
Denmark B Theory · Understand the traps and how to avoid them.
At a four-way intersection with no signs or markings, the candidate stops and then proceeds without yielding to traffic approaching from the right, or yields when the other car is actually on the left.
Candidates memorize 'right before left' as a slogan but fail to scan the full intersection, misjudge which approach is genuinely from the right, or freeze and wave through a car that has no priority. The rule feels abstract until it is applied at speed.
What to do instead
Before every unregulated intersection, do a deliberate three-step routine: reduce speed, scan all four approaches, and identify the vehicle whose path crosses yours from the right. Say the priority out loud during practice ('car on my right has priority'). Practise on quiet residential junctions until the scan becomes automatic, then move to busier ones.
Approaching a yield or slip-road merge, the candidate treats it as a stop sign, brakes hard on the acceleration lane, and enters the main road far below traffic speed.
The candidate confuses 'give way' with 'stop' and is afraid of being judged for not stopping. This creates a speed differential that is itself dangerous and shows poor merging judgement.
What to do instead
Learn the difference in behaviour: at a yield line you adjust speed to slot into a gap, and you only stop if no gap exists. Practise on a slip road by matching the speed of traffic in the mirror before the merge point, then choosing a gap. Remember that a full stop is required only when traffic demands it or a stop line is present.
The candidate rolls through a right turn at a junction without a shoulder check, cutting close to cyclists or pedestrians waiting at the corner.
Attention is fixed on the traffic light or oncoming cars, and the nearside mirror and blind spot are never checked. Cyclists filtering on the right are invisible to a candidate who only looks forward.
What to do instead
Build a fixed sequence for every right turn: mirror, signal, position, speed, then a shoulder glance over the right shoulder before turning. Treat the right-hand mirror and blind spot as mandatory, not optional. Practise the sequence until it is done without prompting.
The candidate drives at or just under the posted limit in a built-up area but fails to adjust for parked cars, a school, or wet roads, and is marked down for inappropriate speed rather than for exceeding the limit.
Candidates equate 'not speeding' with 'correct speed' and ignore the second half of the speed rule: speed must suit the conditions. They also miss that limits are maxima, not targets.
What to do instead
Before each drive, identify the hazards that should lower your speed: schools, parked cars, rain, darkness, and junctions. Practise saying the reason for your chosen speed out loud ('30 is the limit but 20 is right here because of the parked cars'). The examiner is assessing judgement, not obedience to the sign alone.
The candidate underestimates stopping distance, especially in the wet, and follows the car ahead too closely at 80 km/h on a rural road.
The two-second rule is memorized as a number but never actually applied. Candidates also forget that wet roads roughly double the braking distance and that reaction distance is added on top.
What to do instead
Use a fixed roadside object and count 'one thousand and one, one thousand and two' after the car ahead passes it. In rain, double the count to four seconds. Learn the approximate dry stopping distances at 30, 50, 80, and 100 km/h and practise braking from each in a safe area so the numbers become physical, not abstract.
The candidate starts the car and drives off without a full seat-belt check, and does not ensure that a child passenger is in the correct restraint for height and weight.
The driver's own belt becomes routine, but passengers and children are overlooked. Candidates also assume any child seat is fine, ignoring that children under 135 cm must use an approved restraint suited to their size.
What to do instead
Make a pre-drive walk-around: driver's belt, each passenger's belt, and a visual check of the child seat's fit and anchoring. Learn the height rule for child restraints and the fact that a rear-facing seat must never be placed in front of an active airbag. Rehearse this check until it takes under thirty seconds.
The candidate answers alcohol questions using the wrong limit, believing that one beer is always safe or that the limit is higher than it is.
The legal limit is a blood-alcohol concentration of 0.5 per mille for ordinary drivers and 0.2 per mille for new drivers, but candidates confuse the two or rely on folklore about 'safe' numbers of drinks. Alcohol elimination varies by person and cannot be rushed.
What to do instead
Memorize the two limits and the fact that the new-driver limit applies for the first three years after passing. Learn that the only reliable rule is not to drink at all if you will drive, and that coffee, food, or a shower do not lower blood alcohol. Practise the arithmetic of standard drinks against body weight only as an illustration, never as a licence to drive.
The candidate drives while tired, relies on open windows or loud music to stay awake, and does not recognise microsleeps as a warning sign.
Fatigue is underestimated because there is no test for it and candidates believe willpower is enough. They also confuse the legal limits on driving hours for professional drivers with the absence of any rule for ordinary drivers.
What to do instead
Treat yawning, heavy eyelids, drifting, and missing a junction as stop-now signals, not as things to push through. Plan breaks at least every two hours on long trips. Learn that the only effective remedies are sleep and a short nap, and that caffeine buys time but does not replace rest.
The candidate fails to scan far enough ahead, reacts late to a hazard, and brakes only when the car in front has already stopped.
Attention is locked on the bumper of the car ahead rather than on the road two to three cars ahead. New drivers also under-use mirrors and do not build a picture of what is happening behind and to the sides.
What to do instead
Practise looking through and past the car ahead to the next junction or bend. Every five to eight seconds, check one mirror in rotation. On approach to any hazard, ease off the accelerator early so you have time to react. The aim is to spot the problem before it becomes an emergency.
The candidate cannot answer basic vehicle-safety questions, such as the legal minimum tread depth, how to check tyre pressure correctly, or what the warning lights on the dashboard mean.
Vehicle knowledge is studied as memorization for the theory test and then forgotten. Candidates often do not know that the minimum tread depth is 1.6 mm across the central three-quarters of the tyre, or that pressure should be checked cold.
What to do instead
Learn the key figures: 1.6 mm tread minimum, pressure checked when cold, and the meaning of the red and amber warning lights. Physically check your own tyres and lights once a week so the numbers attach to a real task. Know that worn tyres increase stopping distance, especially in the wet.
