Traffic circles: Do you really know who has right of way?

Sound familiar?

Traffic circles are designed to keep traffic moving safely and efficiently, but they can quickly become a source of frustration when motorists are unsure about right of way, lane choice and indicators.

So, let’s go back to basics.

First: Not every “circle” is the same

South African roads have both roundabouts (often simply called traffic circles) and mini-circles, and knowing which one you are approaching matters.

At a conventional roundabout, motorists must slow down, observe the signs and road markings and, unless directed otherwise, yield to traffic approaching from the right within the roundabout where it presents a danger or potential danger.

A mini-circle works differently. Here, you give way to a vehicle that crosses its yield line before you and would cross your path. In simple terms, the vehicle that reaches and crosses the yield line first generally has priority.

Whatever the type of intersection, always pay attention to the signs and road markings - they may specifically direct how you must proceed.

What about a single-lane traffic circle?

Keep it simple.

Slow down as you approach, check for traffic with right of way and enter only when it is safe. Travel clockwise around the circle and use your indicators to make your intentions clear.

Taking the first exit? Indicate left on approach.

Taking a later exit? Indicate left in good time after passing the exit before yours. Once you have indicated to leave, take the next exit.

And remember: a yield sign does not automatically mean you have to come to a complete stop. If the way is clear and it is safe to proceed, you can continue.

And those double-lane circles?

This is where things often become interesting.

The golden rule is to choose the correct lane before entering and follow the arrows, lane markings and signs provided.

As a general guide, if you are taking the first exit, approach in the left lane. If you are travelling further around the circle, the appropriate lane will depend on your intended exit and the road markings.

Most importantly, don't suddenly cut across another lane because you've realised your exit is approaching.

If you need to change lanes, check your mirrors and blind spot, indicate and only move across when it is safe. If you cannot safely reach your exit, go around again rather than swerving across traffic.

A few extra seconds are far better than an accident.

Indicators aren't optional decoration

Indicators help other road users understand what you intend to do.

If you are taking the first exit, indicate left as you approach. For subsequent exits, indicate left in good time before leaving the circle. At mini-circles, indicate left or right according to the direction in which you intend to travel; if you are continuing straight, no directional signal is necessary.

And don't rely entirely on someone else's indicator. A flashing light doesn't guarantee that the driver will actually turn.

A little patience goes a long way

Traffic circles work best when everyone follows the same rules.

Slow down. Choose your lane early. Read the road markings. Give way where required. Use your indicators. Look out for pedestrians and cyclists, and remember that buses and trucks may need more than one lane to negotiate a circle safely.

And if another motorist gets it wrong? Avoid turning it into a contest over who is right. Drive defensively and prioritise avoiding a collision.
