junctions. It is safest to cross the tracks directly at right angles.  Other road users should be aware that cyclists and motorcyclists  may need more space to cross the tracks safely.  307. Overhead electric lines.   Tramway overhead wires are normally  5.8 metres above any carriageway, but can be lower. You should  ensure that you have sufficient clearance between the wire and  your vehicle (including any load you are carrying) before driving  under an overhead wire. Drivers of vehicles with extending cranes,  booms, tipping apparatus or other types of variable height  equipment should ensure that the equipment is fully lowered.  Where overhead wires are set lower than 5.8 metres, these will be  indicated by height clearance markings - similar to ‘low bridge’  signs. The height clearances on these plates should be carefully  noted and observed. If you are in any doubt as to whether your  vehicle will pass safely under the wires, you should always contact  the local police or the tramway operator. Never take a chance as  this can be extremely hazardous.  highwaycodeuk.co.uk 154
