Drivers on Interstate 10 in Arizona, right by Exit 155, can now spot Tesla's Supercharger logo sitting next to the usual gas and food signs, according to Not a Tesla App.
For years, Tesla didn't bother with signs like this because the cars' trip planner already handled directions. Now that other car manufacturers are plugging into the Supercharger network, however, having a marker on the road makes sense in a way it didn't before.

With most automakers building around the North American Charging Standard (NACS), drivers now see Superchargers as part of the broader electric vehicle charging network.
A sign on the highway may seem small, but to someone in a Ford F-150 Lightning or a Chevy Equinox EV, it serves as a quick reminder that a charger is conveniently located right off the exit. This bit of visibility helps reassure drivers who might worry about running low on charge.
Over time, it could pull more traffic to the stalls, potentially bringing in extra revenue.
Rules are shifting, too. A Kentucky NACS ruling required federally funded public chargers to include Tesla's plug, marking a major step for NACS adoption.
At the same time, Tesla has rolled out small updates for owners, including solar charging features and an air mattress accessory. These updates show that the company is continually testing new ways to add comfort and reduce pollution.
That said, Tesla reports show that sales in the first half of 2025 slipped, with deliveries falling short of earlier streaks. Tesla bounced back in Q3 with a record number of deliveries before EV tax credits expired in the U.S.
While EVs pollute less than gas cars, transportation still produces about 16% of harmful carbon pollution, according to Our World in Data. Highlighting charging stations along highways could encourage even more drivers to switch to EVs and push that number down.
Home charging typically costs significantly less than drawing power from a public station, potentially saving hundreds of dollars annually. Qmerit helps homeowners interested in setting up Level 2 chargers by providing free, instant estimates.
