This is Cricket Lane in Lichfield; there are houses on the left, close to the road and yet the speed limit is 40 mph (at least there are a few repeaters to remind you).
The above picture is Cappers Lane, also in Lichfield and the limit is 30 mph. it really doesn’t look like it and two things are true. Most of the traffic on this road will be exceeding that limit and people fail their driving tests every day on this stretch of road. So use the tips from Part One to help work out the limit; a driving test examiner will be quite forgiving if you drive a little below the limit for a short period (while you work it out).
