Advanced Gear Changing

Block gear changing means that after braking to the speed you need, you press the clutch once and move straight to the gear that suits your new speed, missing out intermediate gears rather than shifting through each one in turn. Common examples include changing directly from 4th to 2nd before a sharp turn, from 5th to 3rd when approaching a slower road, or from 6th to 3rd on a slip road approach.

This approach is far more efficient than sequential downshifting because it requires fewer clutch depressions and minimizes moments when your hand is off the steering wheel. With modern vehicle brakes, block changing is easier on the car and improves fuel economy. Examiners welcome this technique as it reflects the DVSA's modern, eco-safe driving standard.

Block changes can also be used when accelerating. For instance, when joining a fast-moving road, you might accelerate briskly in 3rd gear and then skip straight to 5th once up to cruising speed, provided road conditions and traffic flow permit.

To drive economically, use the highest suitable gear for your road speed without allowing the engine to labour or shudder. Lower gears (1st and 2nd) deliver high turning power but use many engine revolutions for very little forward travel, consuming significantly more fuel. Higher gears (5th and 6th) keep engine revs low and run far more efficiently once cruising.

When driving on a dual carriageway or motorway, get into your top gear (5th or 6th) as soon as speed and traffic conditions allow. Maintaining a steady pace in top gear lowers fuel consumption, reduces exhaust emissions, and creates a quieter, smoother journey.

Engine braking happens when you release the accelerator pedal while the car remains in gear. The natural mechanical resistance of the engine helps hold the vehicle back and slows the car down without relying solely on the footbrake.

On a long or steep downhill descent, select a lower gear (such as 3rd, or 2nd on very steep gradients) before beginning the descent. The engine's compression will help hold the car back so you only need light, intermittent taps on the footbrake. This prevents your brake pads and discs from overheating and losing effectiveness through brake fade.

Always reduce your road speed with the footbrake before changing down into the lower gear. If you force a downshift at too high a speed, you risk over-revving the engine and causing a sudden, destabilising lurch.

Always choose your gear to suit the road gradient. When climbing steep hills, shift down early into a lower gear to provide the torque needed to prevent the engine from labouring. On level ground, shift up to keep revs moderate.

Avoid resting your left foot on the clutch pedal or keeping your left hand resting on the gear lever while driving. Riding the clutch slips the plates and wears them out rapidly, while pressure on the lever causes premature wear to the internal gearbox selector mechanism.

Make every downshift smooth by matching your road speed with the footbrake before engaging the lower ratio. Listening to the engine helps you avoid both labouring (a deep groaning shudder at too low revs) and over-revving (a high-pitched whine from excessive revs).

In icy or snowy weather keep revs low and inputs gentle, and pull away in 2nd (or 3rd on very slippery surfaces) as the Highway Code recommends using as high a gear as possible; in deep water or ford conditions see the fords and floods topic below.

When setting off on gradients, secure the vehicle using the handbrake to prevent rolling backwards or forwards before finding the biting point. Precise coordination for steep gradients is explored in detail in the later dedicated hill-starts lesson.

Only enter standing water or a ford if you can judge that the water is not too deep. At a designated ford, always check the depth gauge or marker board before committing. If there is no depth marker, if the water looks too deep, or if you feel any uncertainty, do not attempt to cross; turn around and find an alternative route.

If the roadway or ford is narrow, allow oncoming vehicles to pass through first so you never have to stop or queue while submerged. Enter the water smoothly and drive slowly and steadily in a low gear. Moving slowly prevents creating a bow wave that could wash up into the engine bay or get sucked into the engine air intake.

Keep the engine revolutions elevated throughout the crossing, slipping the clutch slightly if necessary so the car moves at a steady crawl without stalling. Maintaining higher revs prevents water from being forced up into the exhaust pipe. Avoid stopping at any point while in the water.

Water on the brake linings significantly reduces braking efficiency. After leaving the water, test your brakes gently at the first safe opportunity. Continue driving slowly while applying light pressure to the footbrake pedal so the friction generates heat and dries the brakes thoroughly before you resume normal driving speed.

Official Highway Code guidance for driving in adverse weather conditions states that on icy roads you should drive at a slow speed in as high a gear as possible and accelerate and brake very gently. High engine revolutions in a low gear generate excess torque, which easily breaks tyre traction and spins the wheels.

In practical driving, this means pulling away in 2nd gear, or even 3rd gear on exceptionally slippery surfaces, instead of 1st gear. Selecting a higher gear reduces the turning force delivered to the driven road wheels, dramatically cutting the risk of wheelspin and helping the tyres key into whatever grip exists.

To pull away successfully on ice, release the clutch pedal exceptionally slowly and smoothly with minimal accelerator pressure. This principle is very similar to moving off on a steep downhill gradient, where a higher gear such as 2nd is used because gravity is already assisting forward motion; on icy slopes, the same delicate technique applies.

Avoid any sudden or harsh steering, braking, or acceleration. Stopping distances on ice can be up to ten times greater than on dry tarmac, so leave a much larger safety gap between you and other road users. If your wheels begin to spin, immediately ease off the accelerator pedal, allow the tyres to regain traction, and attempt to move off again even more gently.

Eco-safe driving is assessed on every practical driving test. Examiners evaluate your ability to drive in a way that minimizes fuel consumption, reduces emissions, and reduces vehicle wear through intelligent anticipation and smooth control.

Effective forward planning allows you to ease off the accelerator early on approach to red lights or roundabouts, often keeping the vehicle rolling gently and avoiding a full stop. Smooth, progressive acceleration and timely upshifts prevent unnecessary engine strain.

Maintaining correct tyre pressures and removing unnecessary heavy items or roof racks also significantly cuts fuel use. If your car is equipped with an automatic stop/start system, allow it to switch off the engine when halted safely for extended periods in stationary traffic.

Parking safely on gradients requires strict adherence to official Highway Code guidance. Under Rule 252 (Parking on hills), always park close to the kerb and apply the handbrake firmly before turning off the engine.

Leaving the manual car in gear after switching off the engine provides a vital mechanical lock: select a forward gear when facing uphill and select reverse when facing downhill. If you are driving an automatic vehicle, ensure the selector is placed firmly in 'Park'.

Steering wheel position provides an additional safeguard. When parking facing uphill, turn the steering wheel away from the kerb so that if the car were to roll backward, the front wheels would guide against the kerb edge. When parking facing downhill, turn the steering wheel towards the kerb so any forward rolling movement is immediately arrested.

Never park near the brow of a hill where your stationary vehicle presents an unseen obstruction to oncoming or following drivers.
