Distracted and Drowsy Driving
Distraction comes in three flavors, and questions often describe one and ask you to name it: visual (eyes off the road), manual (hands off the wheel), and cognitive (mind off the driving task). Texting is the classic example because it hits all three at once, but a hands-free call is still cognitively distracting - the conversation competes with the road.
What the law targets
Puerto Rico prohibits texting and using a handheld phone while driving. Hands-free use may be permitted for some drivers, but legality is not the same as safety. Other common distractions: eating and drinking, adjusting the radio or GPS, grooming, reaching for a dropped object, and loud or emotional conversations with passengers. Young or inexperienced passengers raise crash risk substantially.
Practical controls
Set the GPS and playlist before you move. Put the phone out of reach. Ask a passenger to handle navigation and texts. Pull over to a safe, legal spot if something truly cannot wait.
Drowsiness
Drowsy driving mimics alcohol: slowed reaction, poor lane position, and gaps in attention. Warning signs include yawning repeatedly, heavy eyelids, drifting out of the lane, missing signs or exits, and not remembering the last few miles. A microsleep - a few seconds of sleep - at highway speed covers the length of a football field.
Countermeasures: stop and rest, take a short nap, share the driving, or stop for the night. Caffeine helps briefly but is not a substitute for sleep. The risk peaks in the early morning hours and mid-afternoon, and after long shifts or untreated sleep problems.
Trap: "roll down the window and turn up the music" is never the right answer - the only real fix is to stop and rest.
Rule of thumb: if you have to ask yourself whether you are too tired to drive, you are.
