What should a driver do if the coupling appears to be failing while driving, such as unusual movement felt between the tractor and trailer?

Pick an answer

1. Speed up to reach the destination before the coupling problem has a real chance to fully fail
2. Slow down gradually and pull off the road safely to inspect the coupling before continuing
3. Ignore the movement since couplings rarely fail once locked
4. Brake as hard as possible immediately regardless of surrounding traffic
