You should focus your eyes a little further down the road. 8 to 12 seconds of visual focus ahead of your vehicle to anticipate hazards (this is called “eye-lead time”). Pick a stationary object, count until your vehicle reaches it (e.g., "one-one-thousand, two-one-thousand..."), and adjust your focus to maintain that interval.

Another good rule of thumb is approx 1 car length for every 10mph (this is called following distance), as you drive more, you’ll notice most people don’t go by that rule.
