Talk to the Comic Book Guy and buy a ticket for the cartoon. Then, go to the Aztec 
Theater to watch the cartoon.

Ride an ATV or Quad:
You can find an ATV or Quad to ride at the trailer park in Homer's and Marge's 
levels. It is between two trailers at the far end.

In Marge's level, go to the trailer park short cut then go near the end of it. You will 
see a card floating on the top of the trailer. Go on the left side of it and you will 
see a blue ATV. 

Faster Money Collection 
Whenever possible, drive through crates and phone booths rather than kicking 
them, as you won't have to waste time running around and picking up your loot. 

Unlimited Time in Timed Missions :
When you start most timed missions in the game, you will be told to get into your 
car, then the clock will start. Instead, don't get in your car, but run to the area you 
need to go, then find a phonebooth or borrow a car. When you get in it, you are 
pretty much finished, and you are already at the goal with seconds(or minutes) to 
spare! 

Multi-Player Racing Game :
Collect all the cards in just one level to unlock the multi-player racing mini game. 

Get Endless Coins :
Go get a car and drive around until you find a wrench nearby. Crash your car 
close by and let it blow up. After it blows up, grab the coins and get in the blown 
up vehicle. Then drive over to the wrench and fix your car and repeat the process. 

Get a Speed Boost 
To get a small boost, stop the car, and then hold the gas, the parking brake, and 
the regular brakes at the same time. Let the tires squeel a little until you see small 
flames. Release both brakes and hold the gas. The car should take off really quick. 

Mini RC Car 
In Homer's last level there is an RC car hidden somewhere in the city. To find it go 
to the Krusty Burger with the firetrucks next to it. Go to the second firetruck and 
jump on the ladder and head for the firetruck's roof. There will be a mini RC car 
and a Bumblebee camera. Destroy it and have fun with your mini RC car. 

Easter Egg: Holiday Look 
Change your system's internal clock (or play on a holiday) to the dates for 
Thanksgiving, Halloween and Christmas to experience a different game look.  

Drive a boat car:
In level 3, the boat car can be found on the C. Spanker, where there are two big 
boxes next to one big box. Go up, then into the extremely large box on top of the 
two other extremely large boxes.

Drive the monorail:
In Bart's first level, go to the entrance/exit to the highway. Where there is a split 
road, go to the right and up the stairs. You will see a monorail. Go to the front car 
and press Y to drive the first monorail car around.

Note: You can also ride the monorail in Apu's level.

Drive a monster truck:
When on Apu's level, you can get a monster truck, Go to Springfield Stadium. 
Directly next to the fountain is a green monster truck.

Drive Nightboat:
When playing as Lisa, drive any car to the pier and look for the huge oil tanker 
with a Globex sign on one side with a jump in front of it. Jump through the Globex 
sign and drive to the top. Do not drive off. Park your car next to the little 
gap/walkway on the left. Hop out and run up to the first set of crates. Hop up to 
the very top and shimmy around the ledge. Inside the top crate is the Nightboat.

Drive pink Cadillac:
On level 6 with Bart, drive to Planet Hype (right at the beginning of the docks, 
there is a revolving planet there) and go on the roof. The Pink Cadillac is crashed 
into the front of the building in a little slot (facing the Squidport sign). Fall off the 
front of Planet Hype, land on the Cadillac, get in, and drive it.

Drive a rocket car:
In Homer's first level, drive to the power plant at the back of the town. Then, drive 
through the power plant. Once you reach the end, keep going along the road and 
on the left, in front of one of the big gold houses near Mr. Burns' mansion, you will 
find a blue and white rocket car that you can drive around. 

Drive road vehicles:
To drive another person's vehicle, walk up to it, press Y, and drive. This is a lot 
quicker than standing on its roof. When in the vehicle, notice that the person that 
was originally driver is still there. Your character will be in the passenger side and 
you are not controlling them. This happens sometimes with vehicles that you get 
from a phone (for example, Mr. Burns' limo that Smithers is driving).

Giant chessboard:
On Homer's first level, drive into the nuclear power plant. You will soon find a 
blocked passage. Get out of your car, jump on the metal things, and double jump 
then press X to break it. Inside are more than 100 coins. When in, hit all of the 
chess people, get the coins, and knock down the trees for a nice amount of coins. 
Note: This place is huge and you cannot get your car in it.

Nuclear death:
At the power plant, go to Homer's workplace. Press Y on the switch.

Watch an arcade game:
When playing as Homer or Marge, go to the Kwik E Mart and walk up to the arcade 
games behind Apu. Press Y and you will be able to watch an arcade game.

Fix car damage:
When your car blows up and you need it back quickly, get in the wreck and drive 
into a wrench. This will return your car to its original form.

Beating Smithers to Mr. Burns:
To beat Smithers to Mr. Burns in the last mission in level 1, purchase the Duff 
Truck from Gil and use it in the race. Immediately when the level starts, drive it so 
it is facing the entrance booth and stop it halfway between the fence and the 
booth. Immediately exit from the car. Borrow a car that is driving into or out of the 
plant to drive to Mr. Burns while Smithers keeps trying to get the truck out of the 
way. If done correctly, he will not be able to do so.

Enable the "Instant vehicle explosions" code. As soon as the race starts, drive into 
Mr. Smithers. He will explode, and you can then just drive to Mr. Burns.

Delivering toxic waste:
On the mission in the level 7 where you have to deliver toxic waste, use any car 
you can hijack the one that you use to pick up the toxic waste. Then, get into a 
fast car or anything else and drive to the school. Now you do not have to worry 
about exploding the toxic waste. You should see the civilian car driving with the 
toxic waste on the back. Just get into it and complete your mission.

Drive Skinner's sedan back to the arcade:
On the last part of the mission, get out from there and go back to talk to Dr. Nick. 
From there, collect Skinner's meds and walk back to the arcade. The clock will not 
start as you have not gotten into a vehicle yet.

The moon from Abe's Odyssey:
In Bart's level 2, go down to where the shipwreck and the red is running into the 
water at the Squidport. Look at where the lighthouse is shining. When the light 
faces backwards, it will shine on the moon that is in Abe's Odyssey, with the hand 
print on it.

Clueless mission: Easy completion: 
In level 3 in the Clueless mission (the second one where you talk to Milhouse a 
lot), drive your car to Wall E. Weasle's. Then, talk to Milhouse at the Noiseland 
Arcade. When you get into your vehicle, you will have already be there. Then, 
before you talk to Milhouse, drive to Planet Hype. Then, go back and talk to 
Milhouse. Run to your vehicle and enter it. The vehicle should be at Planet Hype. 
You should have completed the task. Then, before you talk to Milhouse again, 
drive to the Springfield sign. Run back and talk to Milhouse. Then, run to your 
vehicle. Enter it, and you should now be done with this task. Exit the vehicle then 
talk to Milhouse to complete the mission. Note: This only works if you do it before 
you talk to Milhouse.

Win all street races:
Enable the "Instant vehicle explosion" and "Invincibility" codes then enter a street 
race. Bump into all the racing cars and they should explode. If done correctly, you 
will win every street race that you enter. 

Easy mission completion:
Note: This trick only works with missions that ask you to find a car and travel to a 
location in a limited amount of time. When you cannot complete a level because 
time runs out before you can reach a location, just find out where the location is 
and fail the mission. Then, try the same mission again, but run to the location 
instead of driving there. The timer will not start counting down until you enter a 
vehicle.

For some of the missions (for example, Clueless) where you are instructed to get 
in your car, before the mission starts park your car in front of the check point. 
Then, talk to the person you are supposed to speak with. After talking to the 
person, jump on a car traveling in the direction of where you parked your car and 
ride it to your destination. Note: Do not hijack the car -- just hop on top of it. The 
car will keep going.

Krusty's shortcuts:
In any level, look for a glass window with Krusty's face and the words "Buzz Cola" 
on it. If you drive through it, it is usually a shortcut to get to where you need to 
go. Sometimes it reveals a hidden area.

Burning rubber:
When you are about to start a new game, go to options menu and enable the "Fast 
cars" and "Red brick car" codes. In Homer's first level, get the rocket car and it 
will be the little red brick car. Get in it then hold L until you are at a complete stop. 
Keep L held and you will start to skid flames for a moment.

Speed boost:
On any mini-race (bonus game), you can get a special speed boost. Once you 
have started the race, click the Left Analog-stick. It should give you a nice 
advantage over your opponent. Note: This only works once or twice -- use it 
wisely. It is recommended that you use it just as the race starts.

Decrease Hit And Run meter:
When you are almost going to activate the Hit And Run, get out of your car and 
borrow the first car you can find. Do not drive one from the telephone. Then, 
quickly get out and enter your car again. The Hit And Run meter will reach zero.

When you reach Hit And Run status, get out of you car and walk into a building. 
Wait until your Hit And Run meter goes down, then leave and get back in your car. 

The easiest way to get away from the cops is to jump out of your car and go into a 
house or store. This works best in level 1 with Homer, as you can go into the Kwik-
e-Mart or the Simpson's home. 

Enable the "Instant vehicle explosions" and "Invincibility" codes. When you 
accidentally activate the Hit And Run meter, just remain still inside the car. When 
the police touches you, they will explode before you get busted and your car will 
not explode. 

Get a ride:
Go to any level (Homer's first level recommended). Stand in the middle of the 
road and when a car appears, jump onto its hood then jump again onto the roof. It 
will take you all around the district.

If you hop on top of any of the cars in level 1, they will give you a free ride and 
Homer will do a dancing motion. Often, they will lead you to the races.

Blow up police cars:
Enable the "Invincibility" and "Instant vehicle explosions" codes. Park your car 
next to a passenger and get out. Start kicking them until you get a Hit And Run. 
When a police car arrives, get into your car and you will not get busted. The police 
cars will get blown up.

Avoiding the police:
Enable the "Super jumps" and "Invincibility" codes. When you get a hit and run, 
constantly jump to avoid them. If you enable the "Instant vehicle explosions" 
code, you will be able to destroy them if you jump and land on a car. This trick is 
also useful for avoiding the mob, etc.

Alternate character reactions:
When you buy different costumes, in each level the character you select will react 
differently when you allow him or her to remain idle. For example, choosing 
Bartman will have Bart jump up and fly around for a few seconds.

Seriously damaged car:
On Homer's final levels, drive the 70's car to the yellow bridge that 
reads "Evergreen Terrace and Power Plant". Speed out of the cemetery, drive onto 
the bridge, and ram the car into the railings on the right-hand side the bridge to 
get them merged into each other. Get out from the car and watch it fall. If it does 
not fall, push it. Make sure it falls directly next to the bridge. It will then appear 
from the purple water. Merge through the road completely damaged almost 
exploded. This also happens when the "Invincibility" code is enabled.
