Rules and practical advice for negotiating Roundabouts

When in Dublin, I was surprised a friend had no idea about the basic rule of roundabouts. He cycles into town everyday, but didn’t know at roundabouts you are supposed to give way to traffic coming from your right.

I only noticed because at one roundabout. I waited, and he just cycled on into the path of a car causing it to slow down. He was actually surprised to learn you were supposed to give way. Maybe he spent time in Paris or something, where it really is ‘first come first served’

The Basic Practical Rules of Roundabouts.

  • Give way to traffic on the roundabout. Only join, when it is safe.
  • If you are taking last exit or effectively turning right, you should signal right and ideally be in the right hand lane.
  • The highway code states that cyclists can stay in the left hand lane, even if taking last exit. If you do stay in the left hand lane it is important to signal right, until before the last exit where you signal left to turn off the roundabout.
  • However, I like to look over my shoulder, and if reasonably safe I will signal right and move into right hand lane. I think this is better than staying in left hand lane. True, the highway code says cyclists can stay in left hand lane, but, in practical terms many motorists may not know (or expect) that.

Rules When on Roundabouts.

  • When on a roundabout, you should in theory have right of way over cars joining. However, you can’t take it for granted people will follow the rules, especially at mini roundabouts. When I’m on a roundabout, I try to eyeball any driver joining because some may join anyway.
  • Signal left when you come off, and make sure a car isn’t overtaking on the inside.

If you feel unsafe at very large roundabouts, you can always dismount and go across each intersection.

Mini Roundabouts

Mini roundabouts are becoming increasingly common. But, by experience suggests people become even more insecure about who has right of way – or people conveniently forget.

If the cyclist was turning right, a majority of motorists do not give way, but keep going straight across the roundabout. If you are not aware that most cars will keep going, an accident is quite likely.For some reason, motorists don’t see the give way markings on the road or don’t really see it as a roundabout.

This is on my commute home. It is very rare a car, will stop to allow you to go round the mini roundabout and come off. If you want to avoid an accident, the onus seems to be on the cyclist to give way to the motorist driving straight on. I’ve learnt from experience, never expect the car to give way.

Really big roundabouts that deter cyclists

Cycle Paths

Some roundabouts are just too big, busy for cyclists to feel safe. This can be a major deterant for cyclists making a journey to work. This is Headington roundabout in East Oxford. There is actually an underpass under the roundabout. It is not ideal, because signs tell you to dismount, it takes ages to walk.  But, it’s worth taking the safer underground route.

Cycle PathsUnfortunately, the lack of planning has left many roundabouts which are deter ants for cyclists. But, usually there is a solution, such as avoiding the roundabout or walking around.

 

The Highway code on Roundabouts

160. On approaching a roundabout take notice and act on all the information available to you, including traffic signs, traffic lights and lane markings which direct you into the correct lane. You should

• use Mirrors – Signal – Manoeuvre at all stages
• decide as early as possible which exit you need to take
• give an appropriate signal (see Rule 162). Time your signals so as not to confuse other road users
• get into the correct lane
• adjust your speed and position to fit in with traffic conditions
• be aware of the speed and position of all the traffic around you.

161. When reaching the roundabout you should

• give priority to traffic approaching from your right, unless directed otherwise by signs, road markings or traffic lights
• check whether road markings allow you to enter the roundabout without giving way. If so, proceed, but still look to the right before joining
• watch out for vehicles already on the roundabout; be aware they may not be signalling correctly or at all
• look forward before moving off to make sure traffic in front has moved off.

162. Signals and position, unless signs or markings indicate otherwise.

When taking the first exit
• signal left and approach in the left-hand lane
• keep to the left on the roundabout and continue signalling left to leave.

When taking any intermediate exit
• select the appropriate lane on approach to and on the roundabout, signalling as necessary
• stay in this lane until you need to alter course to exit the roundabout
• signal left after you have passed the exit before the one you want.

When taking the last exit or going full circle
• signal right and approach in the right-hand lane
• keep to the right on the roundabout until you need to change lanes to exit the roundabout
• signal left after you have passed the exit before the one you want.

When there are more than three lanes at the entrance to a roundabout, use the most appropriate lane on approach and through it

163. In all cases watch out for and give plenty of room to

• pedestrians who may be crossing the approach and exit roads
• traffic crossing in front of you on the roundabout, especially vehicles intending to leave by the next exit
• traffic which may be straddling lanes or positioned incorrectly
• motorcyclists
• cyclists and horse riders who may stay in the left-hand lane and signal right if they intend to continue round the roundabout
• long vehicles (including those towing trailers) which might have to take a different course approaching or on the roundabout because of their length. Watch out for their signals.

164. Mini-roundabouts Approach these in the same way as normal roundabouts. All vehicles MUST pass round the central markings except large vehicles which are physically incapable of doing so. Remember, there is less space to manoeuvre and less time to signal. Beware of vehicles making U-turns.

    Totally agree about right hand lane. I often find that sticking an arm out will have an electric effect on following traffic, I’ve heard brakes squeal occasionally. I like to think that this is because car drivers are sometimes intelligent human beings who can appreciate the situation we’re in and wouldn’t enjoy being there themselves.

    I think roundabouts are still relatively new to the Irish. I lived in Galway for a while and was pretty surprised when I got to the first roundabout only to witness a free for all and I was driving a car at the time. It’s unlikely that anyone is doing this on purpose it’s more that they genuinely don’t know what to do!

    I agree with Min that selecting the right lane for turning right it probably better. The only time I’ve been knock off was when I was in the left lane. The car in the right lane turned left. It was a bit of a surprise.

    I agree it is much safer to go in the right hand lane when turning right. Otherwise you are at risk of being cut up by drivers going left or straight on. If you signal clearly that you want to leave the roundabout you should be fine, if a driver doesn’t let you move over as you exit you just have to stay in the right hand lane until one does!
