A car accident can become even more stressful when the driver who caused it has no insurance. However, being hit by an uninsured driver does not necessarily mean you have no way to recover compensation.

Tiemann Law Firm helps injured people in Sacramento, Roseville, and throughout Northern California understand the insurance coverage and legal options that may be available after a crash.

What Happens If the At-Fault Driver Has No Insurance in California?

What Is Uninsured Motorist Coverage?

Uninsured motorist, or UM, coverage may help pay for injuries when the at-fault driver has no liability insurance. It can also apply in certain hit-and-run accidents. Underinsured motorist, or UIM, coverage may apply when the other driver has insurance, but their policy limits are not enough to cover your losses.

UM and UIM coverage may help compensate you for expenses and losses such as:

  • Medical bills
  • Lost income
  • Future treatment needs
  • Pain and suffering
  • Other accident-related damages

The amount available will depend on your policy limits and the circumstances of the accident. Although the claim is made through your own insurer, the company may still investigate the crash, challenge the value of your losses, or dispute whether certain treatment was necessary.

What Other Coverage May Be Available?

Depending on your policy, other types of coverage may also help. Collision coverage may pay for damage to your vehicle, regardless of who caused the accident. Medical payments coverage may assist with certain medical expenses for you and your passengers.

In some cases, an injured person may also consider taking legal action directly against the uninsured driver. A personal injury attorney can review all possible sources of compensation before determining how to proceed.

What Should You Do After the Accident?

Report the crash to law enforcement and your insurance company as soon as reasonably possible. Collect the other driver’s information, take photos, obtain witness contact information, and seek medical care promptly. Keep copies of medical records, bills, repair estimates, lost-wage documentation, and all communications with insurers.

Deadlines and policy requirements can affect an uninsured motorist claim, so waiting too long may limit your options.

From the very start of my case the Tiemann Law Firm was wonderful. Perter came all the way to my home to sit down and talk to me about my options. He made me and my partner feel very comfortable and promised us he would take the very best care of my case. Peter kept me informed every step of the way and was always on top of things. everything was done in a timely manor and I always felt like I was the only case he was working on because he was so fast. In the end Peter got me back way more money than I ever expected. I would recommend this law firm to everyone. I am very happy with the outcome of my case thanks to the Tiemann Law Firm! Thank you!

I just saw my lawyer Jelena Tiemann on a t.v ad, which reminded me how much she helped when I was in a desperate situation. I just love her! That is why I feel a need to tell everyone. I had a situation that happened & didn’t know what to do, our where to go. I didn’t even know if she could help me or if any lawyer could. All I wanted was it to go away & was afraid most lawyers wanted to drag it out & possibly go to court. For one she was very professional but was very personable (maybe b.c she’s a lady). She didn’t make me feel embarrassed or self-conscious that I did something wrong or was the cause of the situation. She immediately said we should try our best before going to court. Let me handle some paperwork, if at the last we do go to court we have documents. She gave me all the details, pros and cons but reassured me she deals with these cases all the time. She came through and made it as painless as possible. I now have my life back.

The Tiemann law Firm has been very good to me ever since I walked in the door. James and Emily have been very responsive and professional and make me feel comfortable when I start to freak out a bit. Accidents can be pretty stressful and I feel like they’ve gone above and beyond. I’m happy that keep me up-to-date on how my case is going. I appreciate that they make me feel like a priority and that they take my case serious. I have already recommend them to a few friends and family members. God forbid I get into another accident, but if I do, I know exactly where to come for help.
