Although the accident severity may be lessened, drivers are penalized by the additional delay and higher vehicle operating costs (fuel, brakes, etc.). There is no real evidence to indicate that STOP signs decrease the speed of traffic. Impatient drivers view the additional delay caused by unwarranted STOP signs as "lost time" to be made up by driving at higher speeds between STOP signs. Unwarranted STOP signs breed disrespect by motorist who tend to ignore them or slow down without stopping. This can sometimes lead to tragic consequences.
State Law requires the installation of all traffic control devices, including STOP signs to meet State standards adopted by the Louisiana Department of Transportation and Development (LADOTD). Louisiana Statutes, Section 235 of Act 310 of the 1962 Legislature, amended by Act 182 Section 1 of the 1968 Legislature states that the Department of Transportation and Development "shall adopt a manual and specifications for a uniform system of traffic control devices consistent with the provisions of Title 32, Chapter 1 of the Louisiana Revised Statutes, for use upon highways within the state" The statutes also state: "All official traffic control signals or other traffic control devices purchased and installed in this state by an public body or official shall conform with the manual and specifications published by the Department of Transportation and Development"
The installation of a multiway STOP condition must first meet the warrants as set forth in the MUTCD. Any of the following conditions may warrant a STOP sign installation (sec. 2B-4):
STOP signs should not be viewed as a cure-all for solving all safety problems but, when properly located, can be useful traffic control devices to enhance safety for all roadway users.
