Signed Roadways
Signed Roadways consist mainly of higher speed arterial roadways with posted vehicle speeds over 35 mph. On most of McKinney’s existing major arterial roads, the existing pavement width is too narrow to add bike lanes and the speed limit exceeds the thresholds for Bicycle Boulevard or Shared Roadway treatments. The traffic speeds and volumes on these thoroughfares require significant cyclist skill and confidence, but they can be ridden effectively by trained cyclist. In addition, these arterials are, by Texas law, open for use by cyclist.
Bicycle May Use Full Lane signs in McKinney remind motor vehicle drivers that state laws give bicyclists the right to use a full lane on roads where there is insufficient space to share a lane. The aim of these signs is to help keep the roads safe for both riders and drivers.
This signage is in accordance with the Texas Manual on Uniform Traffic Control Devices, a document issued by the Texas Department of Transportation to specify the standards by which traffic signs, markings and signals are designed, installed and used.
