All very good information presented in these posts. It breaks down into the "letter of the law vs. spirit of the law" approach. Sure, parking your car in front of, and blocking, a driveway will probably earn you a ticket... but what if it's *your own* driveway? <img src="images/graemlins/cool.gif" alt="" />

Just remember to use common sense... your judgement isn't likely to be questioned if you felt your safety was at risk by staying on the scene (i.e., raving lunatic waving a gun).

And if you are calling 9-1-1 from a cell phone, please be sure to give the dispatcher your cell phone number, in case they need to call you back and get more details.

Here's a good link (at least for California residents):
