Your combination vehicle's trailer brakes fail while descending a grade. What should you do?

Pick an answer

1. Immediately disconnect the trailer while moving
2. Continue at the same speed since the tractor brakes alone are more than enough to stop the whole loaded combination
3. Use the tractor's brakes and a low gear together, and look for an escape ramp or safe place to stop if needed
4. Shift into neutral to reduce strain on the brakes
