According to the Texas Department of Transportation, you should always call the police in a car accident where:

• There are any injuries.
• There was a death.
• One or more vehicles are so damaged that they can’t be safely moved.
• You suspect that the other driver is under the influence of alcohol, drugs, or both.
• The other driver does not have auto insurance.
• The other driver leaves the scene of the accident.

Unless the accident is very minor, it’s better to call the police to the scene so they can document the accident.
