NZ Road Code Car Test common mistakes
NZ Road Code Car Test · Understand the traps and how to avoid them.
Treating the give way rule at an uncontrolled intersection as 'left turns give way to right turns' in every case, instead of applying the rule that a vehicle turning right must give way to a vehicle coming from the opposite direction that is going straight ahead or turning left.
Candidates memorise a simplified slogan from older material or from overseas driving experience, and never rebuild the rule from the actual turning geometry, so they mis-answer scenario questions where the opposing vehicle is turning left rather than going straight.
What to do instead
Draw the two vehicles as arrows on paper for every practice scenario. Apply the test in order: is anyone turning right across another vehicle's path? If yes, the right-turner gives way. Practise until you can state the rule in one sentence without hesitating.
Stopping fully at every stop sign but rolling through give way signs at speed, and failing to give way to traffic already on the priority road when emerging from a driveway, car park, or unpaved road.
Candidates lump stop and give way into one mental category of 'slow down and check', and they underestimate that emerging from a driveway or private land means giving way to all other traffic, including pedestrians on the footpath.
What to do instead
Separate the two signs into distinct behaviours: STOP means wheels stop and you then give way; GIVE WAY means slow, be ready to stop, and give way only if required. Learn the rule that when entering a road from a driveway, car park, or field you give way to all road users, and rehearse it aloud in practice drives.
Misjudging the following distance needed at open road speed and in wet weather, and answering with a fixed two-second gap regardless of conditions.
The two-second rule is the one number most candidates remember, so they apply it as a universal answer and forget that it is a minimum for good, dry conditions and must increase with speed, rain, towing, or poor visibility.
What to do instead
Learn the gap as a minimum that grows: at least two seconds in good conditions, and roughly double in wet weather or when following a heavy vehicle that blocks your view. Practise counting the gap to a roadside marker on real drives so the number has physical meaning.
Underestimating how long alcohol stays in the body and assuming a sleep, coffee, or a meal makes a person sober enough to drive under the limit.
Candidates rely on how they feel rather than on how alcohol is eliminated, and they confuse 'feeling sober' with being under the legal limit, which leads to wrong answers about morning-after driving and about the effect of coffee or cold showers.
What to do instead
Learn the elimination facts: the body clears alcohol at a slow, roughly fixed rate, only time removes it, and coffee, food, sleep, and fresh air do not speed this up. Anchor the answer to 'time only' whenever a question mentions sobering up.
Answering medication questions as if only illegal drugs impair driving, and not checking whether a prescribed or over-the-counter medicine causes drowsiness.
Candidates think of impairment as an illegal-drug issue and separate it from everyday medicines, so they miss questions about antihistamines, pain relief, and prescription drugs, and they do not know that driving impaired by any drug, including a lawful medicine, is an offence.
What to do instead
Adopt the rule that any substance that makes you drowsy or slows your reactions means you must not drive, regardless of whether it was prescribed. Read the label and ask the prescriber or pharmacist, and treat 'do not operate machinery' as 'do not drive'.
Restating the open road speed limit as 100 km/h everywhere and applying the same limit through roadworks, near schools, or on unfamiliar rural roads.
Candidates learn the default maximum but treat it as a target rather than a ceiling, and they forget that posted signs, temporary roadworks limits, and the need to drive to the conditions can all require a lower speed than the default.
What to do instead
Learn the default urban and open road limits, then drill the principle that the limit is a maximum, not a safe speed. When a question describes rain, roadworks, a school zone, or a blind crest, choose the lower, conditions-based answer even if the default limit is higher.
Treating a Warrant of Fitness as proof the car is safe indefinitely, and not knowing that the car must still be roadworthy every day, that faults found between inspections are the owner's responsibility, and that a WoF does not cover everything.
Candidates reduce vehicle safety to 'has a current WoF' and do not distinguish the inspection interval from the ongoing duty to keep the vehicle safe, so they answer incorrectly on questions about bald tyres, warning lights, or defects appearing after a pass.
What to do instead
Frame it as two separate duties: the periodic inspection (know the interval for the vehicle's age and type) and the continuous obligation to keep the vehicle in a safe condition. Learn that a WoF is a point-in-time check, not a guarantee, and that you must not drive an unsafe vehicle even with a current label.
Not knowing the graduated licence conditions that apply to a restricted licence holder, such as night-time and passenger restrictions, and assuming a full licence is granted automatically after a set time.
Candidates study the road rules far more than the licensing pathway, and they assume progression is purely time-based rather than dependent on holding the restricted licence for the required period and passing the next test.
What to do instead
Build a simple timeline of the licence stages and write the conditions of each stage beside it, including any night curfew and passenger limits for restricted holders and who may supervise a learner. Check the current conditions on the official licensing pages, because these details change.
Confusing the demerit point threshold with the consequences of excess breath alcohol or a serious driving offence, and assuming that a fine is the only outcome of a traffic offence.
Candidates lump all penalties into 'you get a fine and demerits', so they miss that some offences lead to licence suspension or disqualification, that demerit points accumulate to a suspension threshold, and that alcohol offences carry their own penalties independent of demerit points.
What to do instead
Sort penalties into three buckets and learn one example of each: infringement fines with demerit points, accumulation of demerit points leading to suspension, and court-based outcomes such as disqualification for serious or repeat offences. Learn the demerit suspension threshold and the fact that alcohol offences are handled separately.
Missing vulnerable road users in give way and following decisions, such as failing to give way to a pedestrian already crossing at a crossing, passing a stopped school bus, or leaving insufficient space when passing a cyclist.
Candidates focus on the interaction between two cars and treat pedestrians, cyclists, and horse riders as background, so they answer the vehicle-to-vehicle question correctly but miss the part of the scenario that involves a vulnerable road user.
What to do instead
Before answering any scenario question, scan for pedestrians, cyclists, motorcyclists, horse riders, and school buses. Learn the specific duties: give way to pedestrians on a crossing, slow and prepare to stop for a school bus displaying its sign, and leave a safe passing gap for cyclists.
