- For cars without ABS: learn "cadence braking" - basically human ABS. ABS/cadence braking will allow you to brake while turning.
- In fog and very poor visibility: make use of your brake lights often (i.e. dab the middle pedal from time to time) to warn people behind you of where your position is. This is MUCH better than hazard lights.
- In fog: do NOT use your high beams. You're just blinding yourself because the dense fog reflects more dazzling light back to your eyes. You're seeing more light but you actually see less of the road in front.
- Be extra-critical of your wipers. I would recommend replacing them NOW if you haven't done so, because we came from a period of hot summer weather that naturally kills rubber, especially if you left the wiper blades sticking to the windshield.
- Once it rains, the moment you have to turn the wipers faster than the "intermittent" setting, open all your external lights. The idea is not so much to be able to see, but to make your presence known to other drivers and road users. With that logic, running park lights without headlights is a half-baked idea.
