Most EV manufacturers offer a roadside assistance package with your car or you can include it in your leasing package. Recovery services also now offer breakdown cover designed especially for electric cars, while the RAC recently announced it was equipping some of its vans with mobile recharging points capable of topping up stranded EVs.
If you need assistance because you've run out of charge, it won't normally be possible to get your EV moving again, so don't put yourself at risk by trying to get a friend to tow it - leave it to the professionals. Even if you're not a member, major breakdown services including the AA, RAC and Green Flag will come to rescue you.
Before help arrives, check your EV handbook for any restrictions on towing, which may damage the car's systems. While some EVs can be towed, as long as their drive wheels are kept off the ground, others can only be moved on a flat-bed truck. If you're not sure, insist on a flat-bed - it avoids the risk of major damage to your car.
