A Queensland motorcyclist is riding in heavy rain. How should they adjust their following distance?

1. Maintain the normal 2-second following distance as braking performance is unchanged on good tyres
2. Follow the vehicle ahead closely so they can see brake lights sooner
3. Switch to a 1-second following distance so they can react faster
4. Reduce speed and increase the following distance beyond 2 seconds to account for reduced traction and longer stopping distances
