Top tips for renting a car in Illinois

  • When researching a car rental in Illinois, it’s important to understand what is required for the weather before renting the car. As for vehicle types, driving in Illinois during the winter often has snow and ice, so choosing the right vehicle for your trip is helpful. To help maneuver the icy roads, a four-wheel-drive SUV is a smart choice. You also might want to check to see if the car is equipped with GPS mapping to help you get around the state. Some parts of Illinois have tolls, so take a look at the options available, such as passes or devices, that allow you to go through the tolls without stopping.
  • When traveling with young children, it’s good to know the rules for booster or child seats in Illinois when renting a car. For driving a car in Illinois, children under eight years old must be secured in an approved child restraint system, such as booster seats or front and rear-positioned harness seats. Children under two years old and under 40 pounds must be seated facing the rear. Children four to twelve years old can be positioned in a booster seat with a shoulder and lap belt. Most car rental locations in Illinois have child seats available when renting a car, but it’s a good idea to check before traveling.
  • Some travelers renting a car in Illinois might want to take a car across the Canadian or Mexico borders. Most car rental agencies allow travel across a border, but certain rules might exist. Some agencies don’t allow vans or luxury vehicles to cross borders. Others might charge extra insurance or other fees, so it’s good to inquire. Be sure to tell the agency you plan to cross a border, or it could violate the rental policy. If you do plan to cross a border, make certain you have a driver’s license and two other forms of identification. Always tell the border agent how long you intend to stay in the country.
  • When renting a car in Illinois, it’s a good idea to know about the car and the area. For example, if you are renting an electric car, where are the charging stations located throughout the city, and how many are there? Most agencies provide you with a map of charging station locations so be sure to ask.
