Description:	A41 at the A414 Hemel Hempstead junction The slip road off the northbound carriageway peels off on the left here to <a href='http://www.geograph.org.uk/photo/1345170'>TL0405 : Hemel Hempstead: A414 road at the A41 junction</a>. Since this is an A road and not a motorway there is a crossing facility complete with a couple of Give Way signs to enable cyclists to cross over the slip road and carry on along the main carriageway. The two white squares in the main carriageway are markers for use by the Police using VASCAR (Visual Average Speed Computer And Recorder) methods. There will be another set of marks either prior to these, or ahead of them, at a known distance, such that, if a vehicle can be timed between the two marks, usually by helicopter, its average speed can be simply computed. On a more engaging note what a wonderful display of daisies 2009 has brought to roadside verges!
