Slow driving with hazard 4-way flashers on

Do you drive slowly up mountains under 40 MPH with 4-way hazard lights flashing so all behind, day or night know that we are far under the highway speed limit? 

Well, just read to my surprise, this safe driving habit is clearly illegal in most states. 

Map shows a summary of state laws.

Looks like we are only going to turn on flashers when we are parked.

That is strange; all the semis fire the flashers, I do when pulling steep and will continue to do so; seems like common sense!  ^.^d

Wouldn't it be unusual to get pulled over for having your E flashers on.... and ticketed.

Actually when I worked the road nobody used flashers for slow moving then some states had signs saying under 40muse flashers and now they are used everywhere it seems.

We see many "tow boys"in our area,taking auction vehicles down south to repair,many don't have legal lighting so they run the flashers.

We just pulled the grade from camp Verde to flag and every truck I passed had his flasher on, when I drove over the road used my flashers to let the crazies know I was not doing eighty. Just saying,😁👍

Unless someone rear ends you doing 80 I guess. I always turn on the flashers when going up grades at less than 45. It gives the cell phone goggling crowd another clue that they're about to end their life Darwin style. But do what makes you happy.  😉

If they don't see the back of a huge white Motorhome, 2 small yellow lights aren't gonna make any difference, but do what makes you comfortable...🚌

Oh I think that they will see a big white MH, but without the FlAcHeRs they are less likely to realize your traveling 40 mph slower and move over.

When my charge air cooler cracked and I had to head up the 3000 foot climb on I 84 in eastern Oregon, I had my flashers on for over 15 minutes.  I could care less if a police officer didn't like it. I have done the same in New Mexico.

Hazard lights are called that for a reason, if questioned just say your safely proceeding at a reduced rate to a safe area of refuge, while trying to alert overtaking traffic due to an issue. Emergency lights are for speeding.

Actually...........this is California law and probably most states follow.......CVC section 25268 

No person shall display a flashing amber warning light on a vehicle as permitted by this code except when an unusual traffic hazard exists.

It is my understanding that it is a National DOT rule to used your flasher below 45mph for trucks.

 Interesting that there are state laws that conflict over a safety issue. I doubt that everyone is supposed to learn all the different state laws regarding slow speed use of hazard flashers. In the dark climbing grades they alert the speeders in the right lane that there is a slow vehicle ahead. I witnessed a major accident on the 101 in the San Fernando Valley where a car in the right lane was using it as a passing lane and crashed into the back of a slow moving truck causing a domino effect of many cars. Because it was not on a grade and the truck had just entered the freeway no hazard lights were used. Had it been daylight the car might have stopped in time.

We use our flashers if I think the situation warrants it.  If I get stopped by the law, I'll plead ignorance.  Usually works for me.  Wonder why....?

To a certain extent I'm guided by the professional truck drivers. I've not traveled in those States that forbid flasher use, but when I'm driving at a speed that is more than 20 mph below the posted speed limit I'll generally turn the flashers on.

Not only do I use the 4 way flashers on a long, slow grade, if I see a slowdown ahead of me or a traffic hazard on the shoulder, I fire them off then as well. Want to give the morons texting behind me as much notice as possible. Also would rather have a conversation with John Law about hazard flasher laws, than watch him make out an accident report.
