Driving on the left as an American: what to practise before your trip

A general familiarisation guide · Last updated 27 June 2026

If you've spent your driving life on the right, the hard part of switching to the left isn't understanding it — it's that your instincts were trained the other way. Under a little pressure, those instincts fire first. The good news: the handful of habits that matter are learnable, and you can rehearse most of them before you ever collect a car.

What actually changes

When traffic runs on the left, the driver usually sits on the right side of the car, so you'll be positioned closer to the centre of the road than you're used to. Many of the controls you reach for without thinking move too — most notably the hand you use for the gear selector. None of this is difficult, but it all competes for attention in the first few minutes, which is exactly when you least want surprises.

Look the right way — first

The single most valuable habit to rebuild is your default scan direction. When you drive on the left, the nearest flow of oncoming traffic comes from the opposite side to the one your reflexes expect. The fix isn't to memorise a rule in the moment; it's to practise the glance until it's automatic, both behind the wheel and as a pedestrian stepping off a kerb. Slowing down and deliberately checking both ways before you commit costs a second and rescues you from your own autopilot.

Hold your lane position

With the car's seat on the other side, your sense of "where the middle of my lane is" shifts. Drivers new to the left often sit too close to the edge on one side because they're unconsciously placing the car as if they were still seated on the left. Give yourself room, use the full lane, and check your position on quiet roads before busy ones.

Turns and roundabouts run the other way

Turns that cross the oncoming flow now happen in the mirror image of what you know, and roundabouts circulate in the opposite direction — clockwise when you drive on the left. You don't need to overthink the geometry; you need to have seen it enough times that entering and exiting feels familiar rather than startling. Mentally walking through a turn or a roundabout a few times before you arrive does a surprising amount of the work.

Build it before you go

Reflexes respond to repetition, not cramming. A few minutes of focused rehearsal a day in the week or two before a trip beats a single long session the night before. Picture the junctions you'll meet, rehearse the scan, and keep the practice short enough that you actually do it.
