14.7.7 Traffic Control Devices

DLT intersections require clear traffic control devices to guide drivers through the intersection. The main objectives of traffic control devices in DLT intersections are:
  • Position signal heads above the receiving lanes at the crossovers;
  • Provide signage and pavement markings to prohibit wrong-way movements;
  • Provide lane extension striping through the main crossover intersection; and
  • Provide pavement markings and overhead signs as supplemental guidance.
Refer to the
FHWA Displaced Left-Turn Intersection Informational Guide
for more information on traffic control devices at DLTs. The
TMUTCD
remains the primary source for traffic control device standards.
