AIBU to be angry he told her to flag down cars?

Your daughter needs to hand back her driving license. Three lives endangered for no good reason.

Are you kidding me? She should not be driving!

I had to stop on the hard shoulder of the M25 when I had an issue with my car. Not only did I know to get behind the barrier, but the AA left it in no doubt - there were recorded messages even before I got to a person and then the call handler wouldn't do anything until I had confirmed I was out of the vehicle and behind the barrier. When the AA man arrived and parked his bright orange van behind my car, he took the keys of my car and wouldn't let me over the barrier either while he was working on it. It made me appreciate the risks of their job tbh.

What does he think another driver would be able to do to help her?

Never sit in the car. Go behind the barriers. She was a sitting duck for an accident while it was foggy too.

Flagging down cars is not sensible, but staying in the car is also really unsafe especially in fog. Another car could come into you and kill you. She should have been out of the car behind the crash barrier. I would have thought that being run into by a car in fog was actually more likely than someone stopping to help who was dodgy, so it's a bit rich to be "furious with DP" when your advice put your daughter at more risk than his.

didn’t say 8% of motorway crashes..just ‘crashes’ therefore the others mostly off motorways .

So your daughter risked her life, her Dad's life and the RAC person's life because she was scared of driving in a storm? I appreciate driving in bad conditions can be scary and getting off the motorway at the first opportunity would have been a good idea but that means turning at the first junction not stopping on the hard shoulder.

Ye Gods the general lack of general knowledge and common sense just beggars belief.

You can only stop for a breakdown or emergency, I don't think if you were flagged down you could stop without being in trouble, unless there was a clear emergency.

If you break down on the motorway you get everyone out of the car and get as far away from the car and the live traffic as possible. It's that simple. If you don't know this you shouldn't be on the motorway.

The advice to stay in the car at the side of the motorway, in fog, was far more dangerous than the risk from an evil Good Samaritan.

I probably wouldn't have given the advice to flag down a stranger either, but I don't think you can very cross, given the dreadful advice you gave.

I've been helped by random people (men) who offered their help many times. I've always been very grateful and no one has done me any harm.

This.

you are as bad as each other! Your advice was just as stupid as his

The hard shoulder is the most dangerous place to be on the motorway - 8% of crashes happen on it.

Surely wherever the other 92% happen (assume the live lanes) would be more dangerous then??

Better to phone the police as well as breakdown services.more risk from speeding wagons than pervs. Get the other side of the rail and keep your head down.
Nowt wrong with a bit of paranoia at the right time and place.

Madness to stay in the car.
How do people lack the basic risk management skills? it’s scary.
A moments inattention from oncoming traffic and you’re a sitting duck.

Get out of the car and over the Armco barrier to await rescue. Just read the Highway Code.

ALWAYS carry a blanket + coat + torch in the car and sweets / water or cans of drink.

I broke down once on the motorway didn't have AA or anything. Rang from one of the roadside phones. Was adviced as a lone female to sit in the passenger seat of the car until help arrived they arranged a garage and sent a copper out who arrived within 20mins

What on earth was his logic behind flagging cars down? What did he think it was going to achieve? That an off duty AA guy with all the equipment will spot her?

In “massive fog, shite conditions” it’s not unreasonable to expect someone to veer to the left . Not likely anyone would see her waving them down , either, in time to stop.

Some years ago, a woman broke down on a Mway further south, and a motorist stopped, murdered her. Equally, I broke down on the A82 , flat tyre and several motorists stopped to help..being the holidays, most couldn’t as tools were under luggage or didn’t fit the Volvo..my wheel brace was split, wouldn’t catch the nut. One van gave me a lift 20 miles to a garage with the tyre to get it fixed, and another car took me back. ..and yeah, the spare was flat, too. That was my first trip to visit my mother alone, and the last I made without checking the car for tools etc first. Never trusted OH again 600 miles round trip and I bought my own tool kit after it.

Flagging down other cars is pointless, in addition to the risk to her personal safety. What can another driver do to help? All you're doing is providing another sitting duck for passing vehicles to crash into.
She should have got out and stood behind the hard shoulder.

You are missing the point. Firstly it's a personal safety risk because trying to flag down cars on a motorway in fog may well get you killed. Secondly it's illegal for pedestrians to be on a motorway

The correct behaviour is in the Highway Code. Remove yourself to a safe place well behind the barrier and call for assistance on your phone.

As pp have said, always have a warm waterproof layer in your car. I always have a coat and waterproof boots in mine, along with a hi viz jacket and a charged battery pack. And a set of jump leads . . . and a bottle of water.

1. Take your car off the motorway
Try to leave the motorway at the nearest exit or by pulling into a service station.
If this isn’t possible, pull over onto the hard shoulder and stop your car as far to the left as possible with your wheels also turned to the left.
2. Leave your car safely and stand away from traffic
Turn on your hazards and if you’ve broken down at night or visibility is low, use your sidelights too.
Make sure you and your passengers leave the car using the left-hand door, wearing hi-vis jackets if you have them.
Climb over the safety barriers to distance yourself from passing traffic. Wait for help here.
3. Call or report a breakdown online

That wasn't the RAC, that was the OP (person broken down's mother).

Perhaps best not mentioned?
