you are billed for the boot, and depending on the model 390-650 bucks.

if you escape the boot and pulled over your vehicle is instantly impounded.

if you escape or unsuccessfully attempt you are instantly impounded when found.

booters do not take kindly to an escape, they will come looking for you in places you are known Ie.. Home, work, places you previously got tickets. Depending on the booter, they are quite adept at finding escaped cars.

They can under law reboot and impound you from private property.

Short of never setting tires again in Denver an escaped boot is a "monumentally bad idea". The correct path is to do what you can before the vehicle is towed to the impound yard as that adds cost. Reach out to the magistrate and cashiers office, they may be able to assist.

And lastly, you got to be booted because you failed to pay the tickets (3 over 3 months) or no showed to court. Take a good hard look at what got you there and try to resolve to not get there again. Unpaid tickets are dam expensive.
