For a unique invitation, send each guest a small toy car with the party information attached to it.
My favorite "poster" material is old rolls of wrapping paper. They have a white back to them that is perfect for drawing large designs.
Roll out the paper on a table and pencil in the shape of your signs. Rectangular shapes for street signs, triangular shapes for caution signs and hexagons for stop signs. Once you have the outline done and a phrase penciled in you can fill in the signs with crayons, paint or markers.
Car Race
Give each child a toy car that rolls. Mark a starting line and a finish line on the floor with masking tape. The lines should only be a few feet apart. Line all the children up behind the starting line, when you say "go" they should push their car away from them. The car that comes the closest to or passes over the finish line first is the winner.
Car Relay
Divide the group into two lines. Set a box filled with toy cars on the opposite side of the room. The first child in each line should run to the box and grab a car then run back to the line. The next child in line runs and gets a car for themselves. The first group to get a car for each member wins.
Build a goodie bag by putting toy cars, coloring books, stickers, and note pads into a bag and decorating the outside with stickers.
Gift certificates and coupons for child friendly restaurants around town also make great party favors.
Cut the cakes as shown by the dotted lines in the diagram.
Align the two cut sections on the sides of the larger piece to form the front and back bumpers.
Frost the cakes.
Use chocolate donuts or stacks of cookies as the wheels.
Windows can be added to the car using frosting, but my favorite way is to use a fruit roll up snack and cut the shapes from it using a pair of scissors.
