How many seconds ahead should a driver look for an open path of travel?

The correct choice indicates that a driver should look 20-30 seconds ahead for an open path of travel. This interval allows drivers enough time to anticipate potential hazards, evaluate their options, and react appropriately to any changes in the driving environment, such as other vehicles, pedestrians, or obstacles.

By looking 20-30 seconds down the road, drivers can better maintain a safe following distance, adjust their speed, and make informed decisions about lane changes or turns. This proactive approach enhances overall safety, as it provides ample time to respond to developing situations, ultimately contributing to defensive driving practices.
