LTO Motorcycle A/A1 key terms

The priority a road user has to proceed first at a junction, narrowing, or crossing. It is given by signs, signals, or rules, and must never be assumed without checking.

A junction with no traffic lights or working signals. Priority is decided by signs and the general rule, and you must be ready to yield even when you believe you are first.

An inverted triangle sign meaning you must give way to traffic on the road you are entering or crossing. Slow down, look, and stop if necessary before proceeding.

An octagonal red sign requiring a complete stop at the marked line or before the junction. You may only move off when the way is clear and priority traffic has passed.

A sign showing a yellow diamond that tells you the road you are on has priority at upcoming junctions. It removes the need to yield at each crossing until a sign cancels it.

A solid white line across your lane showing where you must halt at a stop sign or red light. Stopping beyond it can block pedestrians or cross traffic.

The sequence of red, red-and-amber, green, and amber signals. Red-and-amber means prepare to go but do not move until green; amber means stop unless stopping is unsafe.

Riding between or past slow-moving or stationary traffic. It is legal in many places but risky, so keep speed low, watch for opening doors and turning vehicles, and never cross solid lines.

Riding between two lanes of moving traffic, often at a speed close to the surrounding flow. Rules vary by country and it sharply reduces the time you have to react.

The area around a vehicle that the rider or driver cannot see in mirrors. Before changing lane, turn your head to check it, and avoid lingering beside other vehicles.

A shoulder glance over your own shoulder before changing position, overtaking, or joining a road. It covers the blind spot that mirrors miss and is essential before any sideways move.

Moving from one marked lane to another. Signal first, check mirrors and the blind spot, judge the gap, and move smoothly without forcing other road users to brake.

The gap you keep behind the vehicle ahead, giving time to stop or swerve. In dry weather use at least a two-second gap and increase it in rain, at night, or behind large vehicles.

The total distance covered from seeing a hazard to coming to rest, made up of thinking distance plus braking distance. It grows with speed and on wet or loose surfaces.

The distance travelled while the brakes are actually applied. It increases with speed, load, and poor grip, and is much longer on wet, gravelly, or oily surfaces.

Slowing the motorcycle by closing the throttle and letting engine compression resist the wheels, often with a lower gear. It reduces brake wear and helps control speed on long descents.

At speeds above walking pace, pushing the handlebar on one side makes the bike lean and turn that way. It is the normal way to steer a motorcycle through bends.

Staring at a hazard so that you steer toward it. Instead, look where you want to go through the bend or around the obstacle, and your path tends to follow your gaze.

A crash in which the motorcycle loses grip and slides down on its side, usually from braking or accelerating too hard in a bend. Keep control inputs smooth to avoid it.

A crash where the rear tyre regains grip while sliding and throws the rider over the high side. It is violent and often follows a rear-wheel slide in a corner.

The grip between tyres and road surface. It falls on wet, icy, gravelly, or painted surfaces, so brake and accelerate gently and lean less in such conditions.

A system that prevents the wheels locking under hard braking by releasing and reapplying pressure rapidly. It helps keep steering control but does not shorten every stopping distance.

The height of the pattern grooves on a tyre. Worn tyres clear less water and grip poorly, so check the legal minimum and replace tyres before they reach it.

The air pressure inside a tyre, set by the manufacturer for load and riding style. Wrong pressure harms grip, wear, and handling, so check it cold and regularly.

A quick inspection before every ride of tyres, brakes, lights, chain, controls, and fluid levels. It catches faults while you are stationary rather than at speed.

The correct slack in the drive chain, set by the manufacturer. Too tight strains bearings and too loose risks the chain jumping or breaking, so check and lubricate it often.

Helmet, gloves, jacket, trousers, and boots designed to reduce injury. Even a short trip at low speed can cause serious damage, so wear full protection on every ride.

A helmet that sits snugly, fastens securely, and cannot be rolled off the head. A loose or unfastened helmet can come off in a fall and offer no protection.

Being easy for others to see, through bright or reflective clothing, a working headlight, and riding where drivers' mirrors and eyes are likely to catch you.

People at high risk in traffic, such as pedestrians, cyclists, motorcyclists, and horse riders. Give them extra space and time, and expect unpredictable movement.

A marked place where people have priority to cross. Approach slowly, be ready to stop, and never overtake a vehicle that has stopped at one.

Passing another road user travelling the same way. Check mirrors and the blind spot, signal, ensure the road ahead is clear, and leave a safe gap before returning.

A continuous white or yellow line marking a boundary you must not cross. It usually warns of limited visibility or a hazard, so overtaking across it is prohibited.

A dashed lane or centre line that may be crossed when it is safe. It marks a boundary, not a guarantee of clear space, so always check before moving over.

The condition of a vehicle being safe and legal to use, with working brakes, lights, tyres, and steering. Riding an unroadworthy machine is an offence and a serious risk.

The maximum blood alcohol concentration permitted while riding, set by law. Alcohol slows reactions and reduces balance, and the safest limit is none at all.

Any condition that reduces your ability to ride safely, including alcohol, drugs, illness, and extreme tiredness. Do not ride when impaired; arrange another way home.

Tiredness that slows reactions and concentration, common on long rides. Take regular breaks, stay hydrated, and stop riding when you notice yawning or loss of focus.

Stopping as quickly as possible with firm, progressive pressure on both brakes, keeping the bike upright and looking ahead. Practise it so it becomes automatic when a hazard appears.

Before helping at a crash, protect yourself and others, switch off engines, warn traffic, and call emergency services. Never move an injured rider unless there is immediate danger.

Lying an unconscious but breathing casualty on their side with the airway open. It prevents the tongue or vomit blocking breathing while you wait for help.
