The Insurance Institute for Highway Safety has tested 16 new booster seats for 2017, all but 3 have earned the agency's highest rating of "best bet." 

The "best bet" rating means a booster provides a good safety belt fit for a typical 4 to 8 year old child in almost any car, minivan or SUV. 

Currently, there are 118 booster seats on the market with this top rating, some even priced as low as $13. 

3 of the 16 boosters were rated "check fit" -- meaning they could work for some children in some vehicles. 

Children ages 4 to 8 are 45 percent less likely to sustain injuries in crashes if they're in booster seats than using safety belts alone.
