			Dear Mr. Pasakarnis:

			This is in response to your February 10 correspondence requesting the Federal Highway Administration’s (FHWA) acceptance of your company’s DL1000L, DL1000W, SDL1000L and SDL1000W sign stands as crashworthy traffic control devices for use in work zones and elsewhere on the National Highway System (NHS).  Accompanying your letter was the FHWA Office of Safety Design form explaining the differences between these stands and previously accepted stands was the material (steel v aluminum) and the length (22 inches v 30 inches) of the legs.  You also noted that all changes to the stands are below the bumper line of an impacting vehicle.  You requested that we find these devices acceptable for use on the NHS under the provisions of National Cooperative Highway Research Program Report 350 “Recommended Procedures for the Safety Performance Evaluation of Highway Features.”

			This letter is the acknowledgement of the FHWA’s acceptance of your request.  The original completed form has been modified by the addition of the FHWA acceptance letter number and the date of our review.  The form, of which a copy is enclosed for reference, will be posted on our Web site in the near future.

			Sincerely yours,

						*/* Signature of Michael S. Griffith */*
