I’ve been triggered into writing this by an old post on the same topic that I’ve just seen and replied to, on the Allstate Safe Driving Blog.
By no means are all “safe driving” writers always accurate enough!
With no disrespect to Allstate or the writer of the piece, it was clearly written by someone with only a reasonable knowledge of the issue himself, despite having referenced various sources. I say this because there were a couple of inclusions which are very questionable.
The first of these was about using the “emergency brake” — a highly inappropriate name for the parking brake — to help stop the vehicle, and my response to that point is shown in my reply to Allstate, below. Having said that, a handbrake is a dramatically safer option that a foot-operated parking brake because, with the button held in, it can be applied much more accurately and released instantaneously without extra risk.
