Belarus GAI Theory B common mistakes
Belarus GAI Theory B · Understand the traps and how to avoid them.
Treating a traffic controller's signals as secondary to a green light or to road signs, and proceeding on the green while the controller's arm is raised or a whistle is blown.
Candidates learn signal heads and signs first and drill them most, so under exam pressure they react to the familiar green light and forget that controller signals outrank traffic lights, signs and markings.
What to do instead
Memorise the priority ladder as a single chain: controller, then traffic light, then signs, then markings. Practise the rule that a raised arm or a whistle means stop for everyone, including vehicles that already have a green, and rehearse this ordering aloud before each mock test.
Entering an intersection on a green light without checking that the exit is clear, then stopping in the box and blocking cross traffic when the queue ahead has not moved.
Learners focus on the light colour as permission to move and treat the junction as a point to cross rather than a space to clear, especially when following a slow queue.
What to do instead
Apply the rule that you may only enter an intersection if you can leave it without stopping, even on a green. Train the habit of glancing at the far side of the junction before the stop line and holding back if the exit is occupied.
Misreading priority at an uncontrolled equal-status intersection, for example turning left across an oncoming vehicle or failing to yield to a vehicle approaching from the right.
The right-hand priority rule and the left-turn yield rule look simple on paper but conflict in the candidate's mind when both apply at once, and exam junctions often hide sight lines.
What to do instead
Reduce every uncontrolled junction to two questions in order: is anyone on my right, and am I crossing anyone's path. Drill the left-turn rule separately, remembering that a turning vehicle yields to oncoming traffic going straight or right.
Choosing the wrong lane or road position before a turn or lane change, then cutting across a solid line or swinging wide into the oncoming lane.
Candidates plan the manoeuvre at the last moment and steer by what looks convenient rather than by the markings, so they cross a solid line or drift into the wrong lane.
What to do instead
Set position early: choose the lane well before the junction, obey lane arrows and solid lines, and complete any lane change only where the line is broken. Practise narrating the intended position at least one block ahead.
Failing to give way to pedestrians at a marked crossing, or overtaking a vehicle stopped at a crossing because the candidate assumes it is parked or slow.
Candidates watch the vehicle ahead rather than the crossing itself, and a stopped vehicle is read as an obstacle to pass instead of a signal that someone may be on the crossing.
What to do instead
Treat any vehicle stopped at or before a crossing as a yield cue. Approach at a speed that lets you stop, scan both sides of the crossing, and never overtake at a crossing where visibility is blocked.
Misjudging stopping and following distance, especially on wet or icy surfaces, and answering distance questions using the dry-road figure.
Candidates memorise one stopping-distance number and apply it in every condition, forgetting that braking distance grows sharply with speed and with reduced grip.
What to do instead
Learn the components separately: reaction distance plus braking distance, with braking distance rising with the square of speed. Attach a multiplier to wet and icy conditions and rehearse a small table of speeds rather than a single figure.
Overtaking where it is prohibited, such as at a crossing, on a bridge, at a blind crest, or where a solid line or sign forbids it, and misreading the end of a no-overtaking zone.
Candidates judge overtaking by whether the road looks open rather than by the markings and signs, and they confuse the start and end of restriction zones.
What to do instead
Build a checklist of overtaking bans: crossings, junctions, bridges, tunnels, crests, bends with limited visibility, and wherever a solid line or sign applies. Learn to read zone signs by direction of the arrows and the side of the road they stand on.
Using lights incorrectly: driving with high beam in built-up areas or toward oncoming traffic, failing to switch to dipped beam, or omitting lights in poor visibility and at night.
Candidates treat lighting as a single switch rather than a set of rules tied to conditions, road type and the presence of other road users.
What to do instead
Tie each light to a condition: dipped beam for oncoming traffic and lit roads, high beam only where it will not dazzle, fog lights only in poor visibility, and hazard lights only for the specific situations the rules allow. Practise switching by scenario, not by memory of a label.
Answering first-aid questions with improvised actions, such as moving an injured rider, removing a helmet, or giving fluids, instead of the safe sequence.
Candidates rely on common sense or film scenes rather than the taught sequence, and they underestimate how dangerous moving a casualty can be.
What to do instead
Learn the fixed order: secure the scene and warn traffic, call for help, check response and breathing, control severe bleeding, and keep the casualty still and warm. Remember that a helmet is removed only if the airway demands it, and never give food or drink to an injured person.
Skipping the pre-drive check and misjudging the vehicle's technical condition, for example driving with worn tyres, a faulty brake light, or an expired document, and answering document questions from vague memory.
Candidates separate theory from practice and treat documents and vehicle condition as memorisation topics, so they neither check the vehicle nor recall the validity rules precisely.
What to do instead
Convert document rules into a short list: which document, who must carry it, and when it expires. Pair it with a physical walk-around routine covering tyres, lights, fluids and warning lamps, and rehearse both together so the rule and the check reinforce each other.
