a ladder, a fire hose, a bugle, a bell, a siren, an axe, a pike, a hydrant, the color red (although lime green, yellow, and white are also used) for a firetruck, a huge wrench (for turning the water on at the hydrant). dalmatians have two strong points, dating back to the days when fire wagons were pulled by horses: first, they are usually deaf, so the clanging of the bells or the tooting of the bugles and the blaring of the sirens don't upset them , and second, many people believe that dalmatians and horses get along exceptionally well.
No they will not be held liable. Your car had a certain height specification before being lowered, the car was made of that height for manufactured reasons. If it was your investment or idea to lower the height of your vehicle from its original standard form then you will be held accountable for everything. The only way they will be held liable is if more causes and incidents on other vehicles occur. If the speed bump is higher or raised unusually abnormal to standard specifications then you may have a case, other wise no.
