Use of Signals
February 15th, 2008Is this a topic which ‘gets you going’? Do you get annoyed when others fail to signal? Does lack of signalling at roundabouts annoy you? Do you give perfect, unambiguous signals or do you simply remember because you always signal ‘automatically’? Do you always check all round, including in your mirrors, before you signal?
Consider the following:
Ahead of you is a junction on the right and a line of parked cars on your side of the road. The driver ahead signals right. Do you:
-
follow close behind him because his signal tells you it’s safe to pass the cars?
-
hold a position further back as he might be turning right?
The first option demonstrates a ‘lemming’ mentality, blindly following another; the second shows you keep your options open and give yourself time and space to assess the situation for yourself, but clearly a right signal at this point is confusing. Vehicle positioning is also a way of communicating our intentions to other drivers; in this case correct position (just left of the centre white line) would say the driver was neither parking nor turning right, therefore he will be overtaking the obstruction, so no need for a signal.
There are numerous examples like this, so how do you know when you should signal? The following questions should help you decide when considering a signal:
-
who am I signalling to?
-
what information do I want to convey?
-
can I be sure drivers will understand my signal?
-
where is the best place to start to indicate? Visually scan for alternatives which could make your signal ambiguous.
-
Does my position, coupled with my signal, confirm my intentions?
Approaching a roundabout with 2 exits, straight ahead and right, would you consider that a left signal would be appropriate to go straight ahead? Well, ask yourself this - would you give a left signal to go straight ahead on a main road whenever there is a road off to the right? Clearly not, this would be very confusing and would most certainly indicate to a following driver that you are about to pull over or turn left (maybe into a driveway). So why should a roundabout with no exit to the left be any different? Signals should never be used to give negative intention - I’m signalling left to confirm I’m not going right! At a mini-roundabout in East Dereham, where there is the option of straight ahead or right, numerous drivers signal left when going ahead, but there is a B&B on the left. I fully expect to see a rear-end collision one day when a visitor is signalling left to go into the B&B but the driver behind assumes the intention is to continue ahead!
So, take care over use of signals. Consider every signal before you give it, check your mirrors and ask the who? when? why? questions first. Then your signals will be of value to others, including pedestrians, and it will have the added effect of making you think about your driving more.
