The Unfamiliar Hire Car at Dusk
You collect a hire car you have never driven at 5:40 pm in mid-winter. Daylight is fading and light rain has just started. The car is a larger SUV than your own sedan, and you are not yet sure where the headlight switch, demister and hazard lights are. You must drive 12 km through suburban streets to a friend's house, then find street parking. Traffic is moderate, the road surface is greasy from a long dry spell, and you are already tired after a full day of work. Your phone is in your bag and you have not set up navigation.
1. What should you do before moving off, and how does the unfamiliar vehicle change your risk?

Before moving off, stop in a safe place and familiarise yourself with the controls you will need: headlights and high beam, indicators, wipers, demister, hazard lights and the park brake. Adjust the seat, mirrors and steering wheel. Set up navigation while stationary, or decide a simple route you already know, because operating a phone while driving is a distraction and illegal to handle.
An unfamiliar car raises risk because your muscle memory does not match the controls, the vehicle's size and blind spots differ, and braking and steering responses feel different. In fading light and rain you also need lights on earlier than you might expect. The greasy road after dry weather means less grip, so increase following distance beyond the normal gap and brake earlier and more gently. If fatigue is significant, a short rest or a coffee stop before leaving is safer than pushing through.
2. You feel drowsy about 4 km into the trip. What is the correct response, and why is 'just a few more minutes' dangerous?
Read the worked answer
Pull over in a safe, legal place, such as a car park or rest area, and take a proper break. A short nap of about 15 to 20 minutes, or a caffeine drink followed by time to let it take effect, are the recognised countermeasures. Do not stop on the shoulder of a busy road unless it is an emergency.
Drowsiness impairs attention, reaction time and judgement, and a micro-sleep can last several seconds, which at 60 km/h covers many metres with no control. The danger of 'just a few more minutes' is that fatigue does not resolve with willpower; the impairment continues and can worsen. Opening a window or turning up music does not fix it. If you cannot stay alert, the safest option is to stop and arrange another way to complete the trip.
