Safety Recommendations H-08-3 through -7

************************************************************

The National Transportation Safety Board makes the
following recommendations to the Federal Highway Administration:

Include in a Manual on Uniform Traffic Control Devices standard the
requirements for HOV-only left exits to have LEFT message plaques on all exit
guide signs and for exit direction (arrow) signs to be positioned next to
pull-through signs at exits with limited sight distance, short ramps, or multiple
route choices. (H-08-3)

Include in a Manual on Uniform Traffic Control Devices standard criteria for the
use of advisory speed limit signs for all interstate exit ramps. (H-08-4)

Evaluate the Manual on Uniform Traffic Control Devices standard for guide line
marking requirements for interstate left exits. (H-08-5)

Work with the National Committee on Uniform Traffic Control Devices to ensure
that the next edition of the Manual on Uniform Traffic Control Devices is issued
as scheduled in 2008 and that the revision comprehensively addresses the
uniformity of HOV traffic control devices, including left exits. (H-08-6)
 
Require a phase-in period of 5 years for supplemental LEFT message plaques in
the standard proposed for the next edition of the Manual on Uniform Traffic
Control Devices. (H-08-7)

The Safety Board also issued five new recommendations to the Georgia
Department of Transportation and reiterated four previously issued
recommendations to the National Highway Traffic Safety Administration
