driving theory micellaneous

including: road studs, instrument panel lights

white studs

mark the lanes or the middle of the road

red studs

mark the left edge of the road

amber studs

mark the central reservation of a dual carriageway or motorway

green studs

mark the edge of the main carriageway at lay-bys and slip roads

green/yellow studs

indicate temporary adjustments to lane layouts, e.g. where roadworks are taking place

reflective road studs mark the lanes and edge of the carriageway

zebra crossings

• black and white walkway with two orange lights, spanning the width of the road

• zig zags on either sides of the road

• BELISHA BEACONS

• no light traffic signal to control traffic flow - right of way is automatically given to pedestrians

• if a crossing is split with a pedestrian refuge in the middle, they should be treated as two different crossings

pelican crossing

• a set of traffic lights, with sets of zig zag lines before and after on either side of the road

• a box with a display and a button will be on each side of the crossing

• pedestrian activated

• has flashing amber light as part of its sequence (only crossing with this)

puffin crossing 

• set of traffic lights with sets of zig zag lines before and after on either side of the road 

• has a pedestrian crossing detector, and a pedestrian kerb detector - crossing becomes more efficient 

• no flashing amber phase 

toucan crossing

• similar to pelican and puffin, but have an additional sign for bikes

• usually found on the outskirts of parks around 4m wide, compared to 2m

• to operate a toucan crossing, cyclists and pedestrians should press the control panel and wait for either the green man/bike to show

• no flashing amber stage

instrument panel warning lights - colour system

• red - urgent, needs immediate attention

• amber/yellow - less dangerous, should be addressed as soon as possible

• green, blue or white - indicate a system is in use or is functioning correctly
