Truck Apron
Truck aprons are found at roundabouts and slip lane A slip lane, also known as a filter lane in the United Kingdom, is a road at a junction that allows motorists to change roads without actually entering an intersection. Some intersections that are controlled by lights offer a slip lane, which a ...s. These allow large vehicles -- trucks, buses, and recreational vehicles -- to navigate the roundabout or turn without striking fixed objects or other motorists. Truck apron construction According to Alberta Transportation, “truck aprons are designed to support the weight of large trucks and help long vehicles turn safely through roundabouts. Truck aprons are between the road portion of the roundabout and the inner circle of the roundabout. On slip lanes, the truck apron is located between the road surface (bitumen) and the sidewalk. Both in roundabouts and slip lanes the truck apron is raised slightly, in an attempt to keep light vehicles on the main road surface. The truck ap ...

Roundabouts
A roundabout is a type of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction.''The New Shorter Oxford English Dictionary,'' Volume 2, Clarendon Press, Oxford (1993), page 2632 Engineers use the term modern roundabout to refer to junctions installed after 1960 that incorporate various design rules to increase safety. Both modern and non-modern roundabouts, however, may bear street names or be identified colloquially by local names such as rotary or traffic circle. Compared to stop signs, traffic signals, and earlier forms of roundabouts, modern roundabouts reduce the likelihood and severity of collisions greatly by reducing traffic speeds and minimizing T-bone and head-on collisions. Variations on the basic concept include integration with tram or train lines, two-way flow, higher speeds and many others. For pedestrians, traffic exiting th ...

Slip Lane
A slip lane, also known as a filter lane in the United Kingdom, is a road at a junction that allows motorists to change roads without actually entering an intersection. Some intersections that are controlled by lights offer a slip lane, which allows cars to bypass the lights when they turn. That helps ease congestion and improves journey times, as people turning do not have to stop at the light but can continue at the same speed. There are two types of slip lanes at intersections: slip lanes that end and require traffic to merge to join the main road and slip roads that continue onto the main road as another traffic lane. Rules In Australia, before entering a slip road, drivers must look to ensure that their blind spots are clear of other motorists, cyclists, and pedestrians. Drivers must then give way to any pedestrians crossing the slip road. Before joining the main road from a slip road, drivers must give way to all other traffic even if it is faced with a give-way or with ...
