You have complied with your LEGAL obligation to provide your details to the other party.

That's it. Wait fror her to contact you, and then provide your insurance details.

I'd wait and tell my insurance about it only when my insurance details had been requested. You never know, she might look at the front of the car, decide the damage is minimal, and not bother getting it fixed.

Don't get in too much of a panic, this stuff happens on a daily basis. Nobody was hurt and presumably damage to other vehicle is light.

Did you exchange details other than name/phone number eg address? Can you contact RR driver to ascertain position? Do you have her car's registration number?

If you've not done so already you should report the incident to your own insurer.

Highway code rule 286 says you MUST:

• stop
• give your own and the vehicle owner’s name and address, and the registration number of the vehicle, to anyone having reasonable grounds for requiring them
• if you do not give your name and address at the time of the collision, report it to the police as soon as reasonably practicable, and in any case within 24 hours. Law RTA 1988 sect 170

There's a tendency in modern era of mobile phones to overlook requirement to exchange address and other details.

Others have covered this pretty comprehensively. The only thing I would add to Bethany as an inexperienced driver is that manouvring in restricted spaces, and especially reversing, involve a lot of skill and patience.

You need to be able to judge how close you are to everything else - a good sense of spatial awareness. If you're uncertain, stop sooner rather than later. Remember, you will never be able to see what's happening at the back of your car as well as you can at the front, but you must do your best, by physically turning your head and using your door and windscreen mirrors constantly.

Reversing is inherently dangerous because of this, and reversing out of a space in a car park when there are other cars and pedestrians passing is especially so. Presumably that's why some drivers reverse in to a space, though that is not my preference.
