Correct sentence
Tow trucks come to help broken-down cars.
Why this is better
- Period: Add a period at the end to finish the sentence.
- Broken-down: When you use the words before a noun (like 'cars'), say 'broken-down' with a hyphen. It tells us the cars are not working.
- Subject and action: 'Tow trucks' is who the sentence is about (the subject). 'Come' and 'to help' tell what they do (the action).
Another way to say it
Tow trucks help cars that have broken down.
