Promotes Uniformity Among Signs at EV Charging Stations
Spaces in front of EV charging stations are not parking spots, they are for electric vehicles while being refueled. Official signs that meet federal and state standards are the best way to communicate this message.
At the dawn of the automobile age, directional road signs were mostly an endeavor by private groups such as the AAA and other automobile clubs. Signs were used by these groups for promotion and branding as much as they were for directions and information. This led to a hodgepodge of directional signage along the roadways. In the 1920s, government began to develop signage standards. The familiar octagonal stop sign, for instance, grew out of those efforts.
Today, we are seeing a similar trend in signs placed at electric vehicle charging stations. Charging station operators often have distinct and different signs. Some seem designed with a priority for branding and style over clarity and uniformity. This leads to ambiguous messaging and more blocked charging stations.
Federal Standards for Parking Signs
Standards for size, shape, color, etc. for signs placed on roadways and parking lots are defined in the Manual on Uniform Traffic Control Devices (MUTCD) issued by the Federal Highway Administration (FHWA). By law, all traffic control devices must conform to these standards.
The FHWA issued a Policy Statement on June 17, 2013 to address regulatory sign standards for electric vehicle charging and parking facilities. The document contains recommended signs with word legends to convey parking restrictions at EV charging stations. Howard County chose to use the R7-113 example provided by the FHWA to post at 31 utility-operated charging stations located at five county-owned sites. These “no parking except while charging” regulatory signs replaced green and white signs with “electric vehicle parking only” and a logo depicting a car with a plug.
