Motorists are confronted with so many identical problems in all countries. Standard symbols are used on traffic signs as much as possible to give us an early clear message of what to do, not do, or expect ahead. Traffic light signals controlling junctions do vary internationally. In many countries a continuously flashing amber light is used to mean that you may proceed if clear, but you must give way to both other cars and pedestrians. In many American States you may turn right against a red light if your way is clear.
Road markings assist drivers make the safest and best use of the road space.
Measurement Conversions . Distance measurements in the UK are still provided in miles and so when faced with kilometres on the continent you may wish to convert them into miles. One kilometre is the equivalent of 0.621 of a mile. Flashing your headlamps abroad means what it's supposed to mean over here, that's the same as the horn. Treat all headlight flashes as a warning, not an invitation.
