As hazard warning lights are used to warn of a hazard, I feel they should flash at, say, twice the regular frequency of a standard indicator.
It's not unusual to be able to see only one side of the car and this would facilitate differentiating between indicating and a genuine hazard.
Some cars' indicators
flash faster when a bulb has gone, but bulbs blowing is rare.

Fast flashing can also indicate a flasher that is nearly worn out, which is also rare. |
|
|
Yes. Yes. Yes. For exactly the reason you state. The number of times I have slowed to let someone out into the traffic, only to find they have their hazards on and I can't see the other light. |
|
|
Maybe a double flash followed by a normal time interval? Everything else seems to be computer controlled these days, why not indicators? |
|
|
Yes. And <rant> how about "I know I'm parked on double yellows on a blind bend, but I've switched these flashing lights on so it's OK" lights too? This could take the form of a big flashing arrow saying "book me, I'm a fool."</rant> |

[ds] Some people treat them as a cloaking device. |

Sigh. I've meant to post this idea for ages, only to find it's already there. Bun [+] |

Why not use Morse code to spell the reason for the stop? |
|
|
"I'm very sorry, sir. I was too busy deciphering the Morse warning to notice that the traffic had stopped, and I ran into your car. You'll be pleased to know that the traffic was stopped because of a broken-down lorry, though... I just need to go and code my own hazard lights now. Can you remember the Morse for c?" |

[d_s] - I was told by a pleeceman that using your hazard lights while parking on the double yellow is a driving offence and gets you points on your license, whereas just parking on the double yellow is a parking offence and will only get you a fine. |

Is it only obvious to me that it should transmit the SOS code?

|

what [Cg] said... well not really unless there was an in-car emergency, but have the turn signals flash in between the 4-ways. |
|
|
Related idea, put the hazards on a separate battery backup, so that if your car dies due to an electrical problem, they still work. |
|
|
But I agree, flash speed isn't the best, since that already varies between cars, but a double flash or something would be distinctive. |
|
|
//it should transmit the SOS code// |
|
|
No it shouldn't. There are many valid reasons for declaring your vehicle a hazard, not all of them requiring emergency assistance. |
