If a car is parked in a loading zone and is hit by another car who is at fault?

It has been suggested that: " Loading zones are usually for delivery trucks or semi trucks delivering goods to the warehouse or store, so if your car was in the loading zone and you were not given permission to unload something you had in the car, then it's your fault for being there in the first place, and if it was just a car going by and it hit you, then they would be At Fault as well." However, this ignores the fact that parked cars usually do not "cause" the collision merely by being there, whether or not legal. Otherwise, drivers would be free to collide with anything that gets in the way in violation of any law. No-parking zones are not usually for protecting other drivers from collisions with parked cars, but rather for the convenience of traffic or abutting businesses. Who is at fault if you hit a car at an expired parking meter? Whether a car is legally parked or not, the driver of every other moving vehicle has a positive obligation to pay attention and stop before hitting it! Simply parking illegally will almost never excuse another driver from hitting the parked car. The parking driver has an obligation to the TOWN to obey the signs, but unlike moving violations, has no obligation to other drivers to follow the parking law, with rare exceptions. You can't sue someone for illegally parking on a public street, especially after you crash into them. No obligation, no negligence, no fault, no payment.
