Items You Should Never Leave in Your Car – Chicago, Illinois Tips

UPDATED: October 13, 2025
Share:

In Chicago, certain items you should never leave in your car include medications, electronics, food and drinks, aerosol cans, and valuables. Exposure to extreme heat or cold in Illinois can spoil or damage these items, and visible valuables can attract thieves. Always take these belongings with you or store them out of sight. 

For expert advice on protecting your car and personal property, contact Insure on the Spot in Chicago at 773-202-5060.

Why Should Chicago Drivers Never Leave These Items in Their Cars?

Chicago’s extreme weather and urban environment make a parked car a risky storage space. For example:

  • Medications: Heat and moisture can alter prescription and over-the-counter drugs, making them less effective. Doctors warn never to leave pills in a hot vehicle.
  • Electronics: Smartphones, tablets, and laptops may overheat or lose battery life in a hot car. High temperatures can even cause internal components or batteries to fail or leak.
  • Food & Drinks: Warm temperatures speed bacterial growth on perishables, raising the risk of foodborne illness. Likewise, plastic water bottles can leach BPA and other chemicals when heated.
  • Aerosol Cans: Pressurized spray cans are flammable and can explode if exposed to high heat. Don’t leave items like spray paint or hairspray on a hot dashboard.
  • Valuables: Wallets, purses, jewelry, and electronics left in view can invite theft. Illinois industry experts advise never storing valuables in a vehicle, and Chicago police recommend locking up and hiding wallets or phones under your seat.

Each of these items can become damaged or dangerous when left in a car. Always double-check for them before you lock up. For Chicago drivers, avoiding these pitfalls helps protect both your belongings and your peace of mind.

How Does Chicago Weather Affect Items Left in Your Car?

Chicago’s seasons are intense, and even short trips can expose your car’s interior to damaging temperatures. Key weather effects include:

  • Summer Heat: On an 80°F day, a parked car’s interior can exceed 110°F in minutes. This extreme heat can melt plastics, spoil food, and permanently damage electronics or medications.
  • Winter Cold: Sub-zero temperatures can freeze liquids (causing bottles to burst) and make glass or electronics brittle. Car batteries and LCD screens are especially at risk in extreme cold.
  • Sunlight & Humidity: Prolonged sun exposure can fade or warp interior surfaces, and high humidity can encourage mold growth on fabrics.
  • Tip: Whenever possible, park in the shade or a garage. Use a sunshade or window visor to keep interior temperatures down. Even briefly leaving items in your car on a hot or cold day can lead to surprise damage.

By preparing for Chicago’s heat and cold, drivers can keep their belongings safer and their insurance claims lower. Just a little foresight can save you expensive replacements.

How Does Chicago Auto Insurance Handle Stolen or Damaged Items?

Understanding Illinois auto insurance is key if something goes wrong:

  • Comprehensive Coverage: In Illinois, comprehensive (other-than-collision) insurance pays for damage to your vehicle caused by events like vandalism or break-ins. For example, if a thief breaks your window, the glass repair is covered (minus your deductible) under comprehensive. However, it only covers the insured vehicle, not your personal items.
  • Stolen Personal Items: Auto policies generally do not reimburse for stolen belongings. The Illinois Insurance Association explains that coverage excludes items inside the car. If valuables are taken, check your homeowner’s or renter’s insurance – these policies often cover personal property anywhere, though limits and deductibles apply.
  • Illinois Requirements: Remember, Illinois law requires minimum liability coverage (usually 25/50/20). Many Chicago drivers add comprehensive or higher limits for extra peace of mind.
  • Preventive Steps: Always lock your doors and keep valuables out of sight, as Chicago police advise. Park in well-lit or secure areas. These precautions can prevent a claim altogether.
  • After a Break-In: If your car is broken into, immediately call 911 and report it to the Chicago PD. Document any damage (photos) and get a police report number. Then call your insurance agent to file a claim for the vehicle damage (remember, stolen items themselves are usually not covered). Finally, take steps to prevent future incidents (lock up, remove valuables) and consider upgrades (alarms or trackers).

Being prepared with the right coverage and habits is the best protection on Chicago roads. Given the city’s weather and crime rates, reviewing your coverage and parking habits is always wise.

Frequently Asked Questions (FAQs)


Q: What’s the minimum auto insurance required in Illinois?

A: Illinois law mandates at least 25/50/20 liability coverage. This means $25,000 per person for bodily injury, $50,000 per accident, and $20,000 for property damage. These are the state minimums to drive legally. Most drivers choose higher limits or additional coverage (like uninsured motorists) for better protection.


Q: Does car insurance cover items stolen from my vehicle?

A: Usually not. Illinois auto insurance covers damage to your vehicle, not personal belongings. A comprehensive policy will help fix your car (for example, a smashed window), but your phone, wallet, or laptop stolen from the car isn’t covered by auto insurance. Instead, homeowners’ or renters’ insurance typically covers stolen personal items (subject to its limits and deductible).


Q: Is it illegal to leave a child or pet alone in a parked car in Chicago?

A: Yes. Illinois law makes it a crime to leave a child under age 6 alone in a vehicle for 10 minutes or more (Class A misdemeanor). Pet laws don’t specifically mention cars, but Chicago takes animal endangerment seriously. In any case, even a few minutes in Chicago’s heat can be fatal. Never leave children or pets unattended in a parked car, especially in hot weather.


Q: How can I protect my valuables when I drive in Chicago?

A: Always lock your car and stash valuables before parking. Place items in the trunk or under the seat (out of sight), and choose busy, well-lit parking spots. Consider a visible alarm, steering lock, or GPS tracker for extra security. These simple steps (recommended by Chicago PD) greatly reduce your risk of theft.


Q: What should I do if I return to my car and find it broken into?

A: First, ensure your safety and call 911 to report the break-in. Take photos of any damage and get a police report number from the Chicago PD. Then contact your insurance agent to start a claim for the vehicle damage (comprehensive coverage applies to the car, not the stolen items). Finally, remove any remaining valuables and revise your parking habits (lock up, park in safe areas) to prevent future incidents.
