Issued: AUG 2007 DO NOT LEAVE VEHICLE OR TRAILER UNATTENDED SIGN RECOMMENDED PRACTICES PART HIGHWAY SIGNS SECTION REGULATORY SIGNS Revised: Page 1 of 2 SUB-SECTION General Safety rest area, roadside turnout, vehicle inspection station, brake check and chain up/chain down roadside facilities along Alberta highways are intended to be used for their specific purpose. For instance, roadside turnout and rest area facilities are intended to be used by travelers wanting to stop for rest or refreshment. It is not intended or desirable for the above mentioned roadside facilities to be used as long-term parking or vehicle storage areas where vehicles or trailers are left unattended for extended periods of time. If vehicles or trailers are left unattended for extended periods, problems with roadside facility capacity may arise, and motorists needing the services may not be able to use the facility. Standard At locations where vehicles or trailers are frequently left unattended for extended periods, the Do Not Leave Vehicle or Trailer Unattended regulatory sign (RC-110) serves to notify motorists of the restriction. A standard RC-110 sign has a square shape and consists of a black message on a white background. The size of the sign is 900 mm x 900 mm. RC-110 Colour Sheeting 900 mm x 900 mm Message and Border Black Background White ASTM, Type III or IV Guidelines for Use In general, Do Not Leave Vehicle or Trailer Unattended signs may be provided at roadside turnouts, safety rest areas, vehicle inspection stations, brake check areas and chain up/chain down areas in situations where vehicles or trailers are often being left unattended for extended periods (i.e., greater than 12 hours), or the department anticipates problems may arise. Issued: AUG 2007 DO NOT LEAVE VEHICLE OR TRAILER UNATTENDED SIGN Guidelines for Placement The sign should be placed within the roadside facility site in a highly visible location with the sign orientated to face the parking area. Sign placement should be in accordance with the Recommended Practices Placement of Signs guideline. Depending on the size of the site, one or more signs may be needed to effectively notify roadside facility users of the restriction.
