CENTRE & RIGHT MIRRORS
AND RIGHT BLINDSPOT

CENTRE to check the SPEED and DISTANCE of oncoming cars so you have a safe gap large enough for you to move into
RIGHT and BLINDSPOT to check nothing is alongside before moving lanes

On a dual carriageway you should be continually refreshing your 360 SAFETY BUBBLE around you.
Then you are ALWAYS PREPARED to move into the right hand lane when safe

Also watch out for cars behind you who may be signalling right, as they may move into the overtaking gap you have planned for
