Driving on a highway - Part 1

Driving on highways are experiences in themselves. An automobile can either be a joy or a nightmare on a highway. One can either be thrilled, elated and happy with the experience or feel stressed, tired and bored even worse a freak incident can cause it to be a nightmare which'll haunt you all your life. Reading Jiya writing for the first time about driving on a highway brought out a certain sense of excitement and discovery. I started driving in 1995 and a Maruti OMNI was the car/van on which I learnt the art and honed it (if one could call it so). City driving demands lots of patience, deft use of the gear & clutch (if you are driving a diesel), lots of attention to the road and mirrors (all three - center, left, right), anticipate a rash bike to cut across or a pedestrian to jump across a median, and most importantly keep your cool given the increasingly stuffed city road, pollution & traffic hold ups. On the other hand to drive on highway one'll need all of the above coupled with an instinct to know when to speed (rip as some would call it) and when to exercise extreme caution. Having driven all over South India on all the highways and most of the state highways if there's one thing that's common to all roads in India then that is their unpredictability. One has to stay ahead of the automobile one is driving performing calculations in real time in one's mind working out the distances in overtaking & braking, knowing when to put your foot down on the accelerator and when to brake so on and so forth.

We all know the risks of highway driving, the speed for one can be deceiving and give one a false sense of safety. With the high speeds modern cars can achieve and the increasing improved nature of our roads the thrill of going overboard on the speedometer is not an easy prospect to fight over. Mind you, I'm not advocating snail's pace on a highway, it beats the whole point. I'm only advocating a more cautioned approach where the drive is majorly convinced of his/her actions. And ofcourse one person's view might just not match with another and hence each one interprets events in their own special way. There are no set rights and wrongs and no one can claim to be immune from an accident. An accident / mishap can happen to anyone, to the aggressive, to the extremely cautious, to all and sundry, one can only take some precautions hoping to remain on the safe side and enjoy the drive. I'd like to cite an example here of an extremely competent drive I know, my brother. This guy is a master of speed, he can do Coimbatore --> Bangalore(340 kms via Sathyamangalam, Mettur) in 5 hrs (minus a couple of minutes). He knows where to bark and where to calm down, sitting with him in the front seat will open your mind to innovative ways of calculating time it takes to overtake a vehicle with oncoming traffic. The way he slips in and out of traffic looks and feels so effortless and one could think it's because of the power in the car he drives but most often he sets the records straight by doing the same on a Maruti 800. Even this guy has had a bad day on the road and the reason was sleepishness. Despite the best of human efforts and thinking there can always be a day when things simply don't go your way, don't fear that day.

Before you hit a highway plan your trip here's some pointers for the layman which are apart from the fact that the vehicle should have been recently serviced and is not due for a service anytime within the next 1000 kms. Most of these are also regular maintenance tips but hold more importance when embarking on long trips.

* Start the engine and let it idle for 2 minutes, closely hear to the engine's hum and try to see if any unnatural ratting, clinging or vibration is observed.
* Switch off, check engine oil level by pulling out the dipstick in the engine. The right way to do this is to pull the dipstick out, clean the oil off it, dip it into the engine and pull it out. Check if oil is within the min/max markings and also see it's colour. Any shade of brown/black means it's time for an oil change (on petrol vehicles this is done every 10000 kms, on diesel's it usually every 7500 kms)
* Check coolant levels and top the wiper water container with fresh water preferably not hardwater/seawater if possible.
* Check all electricals for proper functioning - headlights, turn indicators, fog lamps, horn, electronic locking system.
* Check the aircon and let it run for 10 minutes, try to see if any abnormal smells comes into the cabin like smoking or burnt oil. Make sure the cooling happens normally and watch out for signs of a lag in cooling in which case the gas in the system needs recharging.
* Check brakes and get them adjusted if the pedal is too soft or if biting occurs when braking.
* Start the engine, engage the first gear and release the clutch. The vehicle should get into motion smoothly with no signs of strain or jumping. If the clutch is not in good shape you'll feel the vehicle behaving like a frog getting into motion. This problem needs immediate attention to avoid being stranded on a highway with a broken or faulty clutch.
* Check onboard and confirm that you have a copy of the registration certificate, insurance papers (up to date), emission certificate (irrespective of the state you are driving in), driving license and the first aid kit with basic medication (cotton wool, dettol, paracetamol, saridon/anacin). Do not carry cough syrup. It's okay if a driver coughs for 50 kms before reaching the destination than allowing him to drink cough syrup and sleep midway.
* Check and make sure you have the tools for refitting the tyre on board (spanners, jack and a hazard sign)
* Check tyre pressures, don't miss the spare wheel. Check the pressure early in the morning or late night and don't drive too long to check. The idea is to check cold tyre pressures which are what you find marked on the body. When you drive longer you heat up the air inside the tyres and can cause setting an incorrect value. An Indigo rated is 28 psi tyre pressure normally. After driving 25 kms at 80 kmph the pressure shoots up to 30psi which is perfectly is normal and within the working parameters of the rubber. But if I check pressure at this point then I'll bring the pressure down 2 psi down (to 28 psi because that is what is on the body) which is less than ideal. Make it a habit of checking tyre pressures the first thing in the morning all the time.

We're making an assumption that wheel balancing and alignment has been carried out on the automobile every 5000 kms and the tyres are in good shape. After writing this much I'm tempted to convert this post into a series because summing it all up will make this one HUGE article. So, over to the next part of this post next week. Drive safe folks.
