Overtaking, Lane Discipline and Lane Changing
Overtaking and lane discipline are about predictability. In Oman, traffic keeps right and overtakes on the left. Before overtaking, check mirrors, signal, check the blind spot, ensure the road ahead is clear and that you can return without cutting in. Do not exceed the speed limit to complete the move. Return to the right lane when you can see the overtaken vehicle in your interior mirror.
Where not to overtake
Do not overtake on a solid line, at a junction, on a bend or crest, near a pedestrian crossing, or where signs/markings prohibit it. Avoid overtaking a vehicle that is signalling to turn or is already positioned for a turn. At roundabouts, choose the correct lane before entry and do not change lanes on the circulating carriageway.
Worked example
A truck is doing 70 km/h on a 90 km/h rural road. You check mirrors, indicate left, move out, pass with a clear side gap, and return right only when the truck’s front is visible in your mirror. If a car behind is already overtaking you, wait: two overtaking vehicles can trap you.
Traps
Sitting in the left lane when not overtaking; changing lanes without a blind-spot check; cutting back too early; and undertaking on the right because the left lane is slow. Lane changes should be one at a time, signalled, and made only when the gap is real, not assumed.
