Which way to turn your wheels in all four scenarios, gear selection, handbrake use, moving off on a hill start, and where you must never park on a slope
April 2026 · By BP Driving School · Based on RSA Rules of the Road
Parking on a hill seems straightforward — pull in, handbrake on, done. But a handbrake can fail. On a steep Irish road, a car rolling unchecked into traffic is a serious hazard. The wheel-turning technique for hill parking is specifically designed as a secondary safeguard, so that if the handbrake fails the car rolls toward the kerb or the road edge rather than into the carriageway. There are four distinct scenarios — this guide covers all of them with diagrams.

The logic behind turning your wheels when parked on a hill is simple: handbrakes can fail. A cable can snap, a ratchet can slip, or a driver can accidentally knock the release. If your car starts rolling on a hill with wheels pointing straight ahead, nothing will stop it until it hits another vehicle or injures someone.
Turning your wheels so they are aimed at the kerb or road edge means that if the car moves, the tyre contacts the kerb and the car stops — or it rolls toward the roadside rather than into the carriageway. This is a passive safety backup that costs nothing and takes two seconds.
A rolling car on a hill is a serious hazard. Several road casualties and significant property damage occur each year in Ireland from vehicles that have rolled away from parked positions. The wheel-turning technique is the single most important thing you can do beyond applying the handbrake.
Quick Reference — All Four Scenarios
Hill Parking — All 4 Scenarios at a Glance
Summary of all four scenarios. The only scenario where you turn wheels LEFT is: facing uphill with a kerb. In all other three scenarios, turn wheels RIGHT.
Memory Aid — The Rule in Plain English
Uphill + kerb (kerb is on your right)← Wheels LEFT (away from kerb)
Downhill + kerb (kerb is on your right)→ Wheels RIGHT (into kerb)
Uphill + no kerb→ Wheels RIGHT (toward road edge)
Downhill + no kerb→ Wheels RIGHT (toward road edge)
The only time wheels go LEFT is uphill with a kerb. Otherwise — wheels RIGHT.
Uphill with a Kerb — Wheels Left
When facing uphill with a kerb on your right (the normal left-side-of-the-road parking position), turn your front wheels to the LEFT — away from the kerb, toward the road.
Uphill + Kerb — Wheels LEFT: Why It Works
Facing uphill with a kerb: wheels LEFT (away from kerb). If the car rolls backward, the wheel arc brings the rear tyre against the kerb, stopping the car before it enters the road.
The logic: if the car rolls backward (downhill), the steered front wheels track toward the road — but the rear wheel quickly contacts the kerb on your right side, stopping the car before it can enter the carriageway. This is counterintuitive to many people who instinctively feel the wheel should be turned toward the kerb — but turning toward the kerb when facing uphill would cause the car to roll away from the kerb if it moves backward.
Downhill with a Kerb — Wheels Right
When facing downhill with a kerb on your right, turn your front wheels to the RIGHT — toward the kerb.
Downhill + Kerb — Wheels RIGHT: Why It Works
Facing downhill with a kerb: wheels RIGHT (into kerb). If the car rolls forward, the front wheel immediately contacts the kerb, stopping the car from rolling into the road ahead.
This is the most intuitive of the four scenarios — it feels natural to turn toward the kerb when facing a downhill. The front wheel contacts the kerb immediately if the car moves forward, providing an instant stop.
Uphill with No Kerb — Wheels Right
On a hill with no kerb — common on rural Irish roads — the logic changes. Without a kerb to catch the wheel, the goal is to ensure a rolling car goes toward the road edge (grass verge, ditch) rather than into the carriageway.
When facing uphill with no kerb: turn wheels RIGHT — toward the road edge. If the car rolls backward, it will arc toward the edge of the road rather than across the carriageway into oncoming traffic.
Downhill with No Kerb — Wheels Right
When facing downhill with no kerb: also turn wheels RIGHT — toward the road edge. If the car rolls forward, it will arc toward the edge rather than into the centre of the road.
No Kerb — Both Uphill and Downhill: Wheels RIGHT (Toward Road Edge)
Without a kerb — both uphill and downhill — turn wheels RIGHT toward the road edge. If the car rolls, it arcs toward the verge or ditch rather than across the carriageway into oncoming traffic.
The no-kerb logic: without a kerb to physically stop the car, the wheel direction simply steers the car toward the least-harmful direction if it rolls — the road edge rather than oncoming traffic. It does not guarantee safety (no physical stop exists), which is why the handbrake and correct gear are even more critical on roads without a kerb.
Gear Selection and the Handbrake
The wheel direction is a passive backup. The two active controls are the handbrake and the gear. Both must be applied every time you park on a hill.
Scenario
Manual — Gear
Automatic — Gear
Handbrake
Facing uphill
1st gear
P (Park)
Always on ✓
Facing downhill
Reverse gear
P (Park)
Always on ✓
The gear provides a mechanical lock against the drivetrain. On a steep hill, this combined with the handbrake gives you two independent failsafes before the wheel direction becomes relevant.
RSA Rules of the Road: "Apply the handbrake. Switch off the engine. Leave the vehicle in first gear or reverse, or, in the case of an automatic, select P." This is stated as a general parking requirement — it is especially critical on any incline.

Where You Must Never Park on a Hill
The RSA Rules of the Road explicitly lists locations that are always off-limits regardless of any other considerations. For hill parking specifically, you must never park:
At the brow of a hill — a parked car at the top of a rise is invisible to approaching drivers until they are almost upon it
At a corner or bend — same visibility problem; approaching vehicles cannot see a parked car around a bend
On a hump-back bridge — both restricted visibility and weight considerations
Where there is a sharp dip in the road — creates an invisible parking spot for approaching traffic
These restrictions exist with no exceptions. Even if wheel direction and gear are perfect, parking at the brow of a hill is illegal and dangerous — another vehicle approaching at speed will have no time to react to a stationary car that appears suddenly over the ridge.
Moving Off on a Hill — The Hill Start
Moving off from a parked position on a hill — particularly facing uphill — is one of the most anxiety-inducing moments for learner drivers. Rolling back while trying to pull away is very common without the correct technique.
Hill Start — The Correct Sequence (Manual Car)
The hill start prevents rolling backward on an uphill. The key is Step 3 — finding the biting point before releasing the handbrake. If the car starts to roll back at Step 4, it means the biting point was not fully engaged.
The most common hill start mistake is releasing the handbrake before the clutch is fully at the biting point. The car rolls back because there is no drive to counter the slope. Always find the bite first — feel the car slightly lift or strain against the handbrake — then release the brake.
On the driving test: the RSA examiner assesses your ability to move off safely — including from a hill. Rolling back more than slightly when moving off is a fault. Use the handbrake technique every time you are parked on any incline during the test, not just on steep hills.
Automatics and Hill Parking
Automatic cars make hill starts significantly easier, but the wheel-turning rule still applies in full.
Always select P (Park) — this mechanically locks the transmission against rolling
Still apply the handbrake — P alone is not sufficient on steep hills (P is designed to prevent rolling when the car is properly stopped, but the pawl can be damaged if it takes the full load of the car on a steep hill)
Turn the wheels using exactly the same rules as a manual car — the scenario (uphill/downhill, kerb/no kerb) determines the direction
When moving off on an uphill: select D, release footbrake — the car should not roll back significantly. Add gentle accelerator if needed
Automatic tip: when stopping on a steep uphill at traffic lights or in traffic, keep the footbrake applied until you are ready to go — then transfer to the accelerator. The slight creep of an automatic is usually enough to prevent rolling back on moderate slopes without using the handbrake. On steep hills, use the handbrake.
Frequently Asked Questions
Turn your front wheels to the LEFT — away from the kerb, toward the road. If the handbrake fails and the car rolls backward, the front wheels will steer the car so the rear tyre contacts the kerb, stopping the car before it enters the carriageway.
Turn your front wheels to the RIGHT — toward the kerb. If the handbrake fails and the car rolls forward, the front wheel immediately contacts the kerb and the car stops.
Whether facing uphill or downhill with no kerb, turn your wheels to the RIGHT — toward the road edge or grass verge. This ensures that if the car rolls in either direction, it arcs toward the edge of the road rather than into the carriageway.
In a manual car: 1st gear when facing uphill, reverse gear when facing downhill. In an automatic: always select P (Park). This provides a mechanical lock as a secondary failsafe alongside the handbrake.
Yes. The RSA Rules of the Road explicitly states you must never park at a corner, a bend, the brow of a hill or on a hump-back bridge. Parking at the brow of a hill creates a hazard because approaching drivers cannot see the parked car until they are almost upon it.
In a manual car: straighten wheels, select 1st gear, raise the clutch to the biting point (feel the car strain slightly against the handbrake), then release the handbrake smoothly while adding a little extra accelerator. The car moves forward without rolling back. The key is finding the biting point before releasing the handbrake.
Yes — always straighten your wheels before moving off. The wheel direction is a safety measure for while the car is parked. Keep wheels turned until the moment you are ready to move, then straighten before releasing the handbrake.
