The North Carolina DOT says it had to remove four electric vehicle charging stations from rest areas due to conflicting state and federal laws.
Transportation officials collected the stations before a state law took effect in March. The law directed the DOT to find a way to charge drivers for using the stations. But a federal law says states can only collect money from rest areas if it comes from vending machines.
The stations were in place for 14 months and the DOT says 146 vehicles used them during that time.
