Service braking distance & Sighting allowance

[mangeshwakankar]

Thanks for the information it is very useful.

There is also quite a bit in the Study Pack including worked examples for several Past Papers; you ought to get it issued to you when you apply to sit the exam.
I posted a draft version of the headway / braking portion on this Forum much earlier in the year: http://www.irseexam.co.uk/attachment.php?aid=1
