What to do in the days following a serious car accident: A guide for expats and international readers

A serious car accident is disorienting at the best of times. When it happens abroad, or in a country where you are still learning how things work, the days that follow can feel even more uncertain. Medical treatment, insurance communications, time off work, and questions about legal responsibility all arrive at once.

Whether you are an expat living in Spain, a visitor involved in an accident overseas, or a reader based in the United States, the immediate priorities are broadly similar, though the specific legal steps will differ depending on where the accident happened. This guide covers the practical actions that matter in the days following a serious collision, with notes on where the process differs between Spain and the United States.

Get medical attention promptly

This applies everywhere. Seek medical care as soon as possible after a serious collision, even if your initial symptoms seem manageable. Soft-tissue injuries, concussions, and internal injuries can develop gradually over hours or days. An early medical evaluation creates a record of your symptoms, examination findings, and treatment plan.

Attend every follow-up appointment and follow the instructions you are given. Missed appointments can be used by insurers to argue that your injuries were less serious than claimed. Your medical records will form the foundation of any insurance claim or legal action.

Report the accident

In Spain: A serious accident must be reported to the Guardia Civil or local police if there are injuries. The officers will produce an official report (atestado) which becomes an important document for insurance and legal purposes. If the accident is minor and both parties agree on fault, a European Accident Statement (Declaración Amistosa de Accidente) can be completed instead. Always keep a copy.

In the United States: Requirements vary by state, but most require police notification when accidents involve injuries, fatalities, or significant property damage. Request a copy of the police report as soon as it is available.

Preserve evidence

Take photographs at the scene if you are able to do so safely, vehicle damage, road conditions, traffic signs, skid marks, and visible injuries. Note the names and contact details of any witnesses before they leave.

Keep all documents related to the accident in one place: the accident report, insurance correspondence, medical bills, prescription receipts, repair estimates, and any records of time missed from work. Do not repair or dispose of damaged property until you have documented it thoroughly.

A daily recovery log can also be valuable. Record pain levels, medication, appointments, and how your injuries are affecting your daily routine. Keep it factual and private.

Handle insurance communications carefully

In Spain: Third-party liability insurance is compulsory for all vehicles. If another driver was at fault, a claim is made against their insurer. Spain’s insurance framework operates under EU directives, and claims must generally be acknowledged within a set timeframe. Be cautious about signing documents or accepting early settlement offers before you fully understand the extent of your injuries.

In the United States: Insurance systems vary significantly between states. Some states operate no-fault systems while others use at-fault frameworks. An insurer may contact you quickly to request a recorded statement. Be careful about what you say before you have received legal advice, casual statements can later be used to challenge the severity of your injuries.

In both countries, avoid accepting a settlement payment before you understand what you are signing. Settlement documents often release all future claims arising from the accident, including claims for ongoing treatment or lasting disability.

Consider Legal Advice

In Spain: If you have suffered significant injuries, consulting a Spanish abogado (lawyer) who specialises in traffic accidents is advisable. Legal aid (turno de oficio) is available in some circumstances. Your insurer may also have a legal expenses cover option worth checking.

In the United States: Personal injury law is handled at state level and varies considerably. If your accident involved serious injuries, consulting a local attorney early can help protect your claim before evidence disappears or deadlines pass. Readers in the Houston area can contact Houston car accident lawyer for a free initial consultation.

In both cases, early legal advice is generally more useful than late advice. Deadlines for making claims, known as limitation periods or statutes of limitations, vary by jurisdiction and can be shorter than you might expect.

Protect your privacy

Social media posts showing physical activity, travel, or comments about the accident can be used against you in insurance or legal proceedings. Privacy settings do not guarantee that posts remain private. Avoid posting accident details, photographs, or opinions about fault or settlement until the matter is fully resolved.

A note for expats in Spain

If you are a foreign resident involved in a car accident in Spain, your right to make a claim is the same as a Spanish resident’s. EU law provides additional protections for cross-border accidents within the EU. Your own vehicle insurance may include legal expenses cover, check your policy documents carefully. If the other driver is uninsured, the Spanish Motor Insurance Compensation Consortium (Consorcio de Compensación de Seguros) may be able to assist.

The practical next step

Gather your accident report, medical records, bills, photographs, insurance correspondence, and any wage documentation into a single secure file. The clearer your records, the stronger your position, whether you are dealing with an insurer directly or seeking legal advice.

A serious accident is stressful enough without the added pressure of administrative confusion. Acting methodically in the days that follow protects both your health and your legal position, wherever in the world the accident happened.
