Lane's Diagonal Rule

Lane's Diagonal Rule

 

There are many rules to use whilst driving to increase our safety.  Some of these rules are well known and relate to Defensive Driving,  i.e. keeping space around our vehicle.  There are 4 Defensive Driving rules - the 2-Second Rule, the Queueing Distance Rule, the Door Width Rule, and - Lane's DIAGONAL Rule.

 

 

Lane's DIAGONAL Rule states -

Always position yourself DIAGONALLY to other vehicles, when travelling in a multilane system at a similar speed to other traffic.

 

 

 

It is necessary to use this rule in any multilane system, that is, anywhere there are 2 or more lanes in your direction and when traffic is travelling similar speeds to each other. You will not be in the blindspot of other traffic when you are Diagonally behind.

 

Lane's DIAGONAL Rule is very valuable in many driving situations, e.g. approaching and negotiating any intersection, especially a crossroads and places where others make a U turn, anywhere large vehicles are turning, and approaching, entering, circulating, and exiting a roundabout.

   

                           

                      Left side driving                                    Right side driving  

                     e.g. UK, Australia                                  e.g. USA, Europe

Positioning Diagonally behind another vehicle means that if another vehicle should suddenly steer into your path, you will not suffer a sideswipe collision. Similarly, if the other vehicle should suddenly brake, you will not be involved in a rear shunt. If the other vehicle is larger, it will also give you physical protection from other traffic crossing into your path, and it will give you a visibility advantage, as the larger vehicle is more easily seen by crossing traffic.

 

At a roundabout, entering, circulating, and exiting, always use the Diagonal rule.

 

                                   

                           Left side driving                                          Right side driving  

Whilst approaching, position your vehicle so you can see behind the vehicle to your offside, so you have a clear view of the circulating traffic approaching you.

 

 

                            

                              Left side driving                                          Right side driving  

Don't assume that a larger vehicle will shield you from circulating traffic. If you drive alongside a vehicle with this assumption, and the other vehicle stops, you will be in the position to suffer the collision.

 

                        

Whilst circulating the roundabout, you must always keep space ahead and to your sides.   When leaving a roundabout, some exit roads have fewer lanes than the number of circulating lanes on the roundabout. If you are alongside another vehicle this will create a major problem for both drivers.

 

 

                         

                               Left side driving                                       Right side driving  

 

If you remain diagonally behind other circulating traffic, where an exit has fewer lanes or only one lane, this will not cause a problem for anyone.

 

Never drive alongside a vehicle especially a large vehicle, always remain Diagonally behind as this avoids most problems and retains an escape route.
