Turn on your sirens and speed across town. You have to get the firetruck to the emergency location before the fire spreads from one tree or building to the next. Start each level in your truck and ready to go. Just follow the arrow on the screen to find the fire. As you drive, watch out for traffic and other obstacles, but don't take your time. You don't want to cause any more emergencies, but you have to reach the fire fast to minimize damage. Once you're there, pull into the indicated parking area and your men will get to work spraying out the flames. When everything's safe again, move onto the next level and head to the next emergency.
