Tyres: Why you check them on a regular basis.

Correct tyre pressure is vital to your safety on the road. Under-inflated tyres affect handling and grip, potentially causing irregular or unpredictable vehicle behaviour. They are also much more likely to suffer from a dangerous blowout, especially on high-speed motorway journeys.
 By keeping your tyres at their correct pressure, your running costs are also reduced. Under-inflated tyres require a bigger force to make them turn, so your car uses more fuel. Additionally, tyres which are not set to their correct pressure wear out more quickly. So, to benefit from lower fuel bills, longer tyre life, increased safety and reduced CO2 emissions, make sure you check your tyre pressures at least once a month.  You should also check them before a long journey, or if you are carrying extra weight in your vehicle
The most basic inspection, which should be carried out at least once a month, is simply checking that your tyres are properly inflated.
Tread depth and tyre condition are also important, remember that the minimum tread depth is 1.6 mm but you should change your tyres before they reach this stage. All tyres are fitted with tread wear indicators which is a little bar connecting the ribs of the tyres. When any of them become visible it is time to replace your tyres.

Performance labelling

A new EC regulation requires some tyres to have performance labels, with the aim of encouraging people to purchase tyres with superior environmental and safety performance, and also encourage tyre manufacturers to produce tyres whose performance exceeds the minimum requirements specified in EU Regulations.
This regulation requires that tyres manufactured from 1st July 2012 for cars, light commercial vehicles and heavy trucks and placed on sale from 1st November 2012, carry a label showing the tyre's wet grip, fuel efficiency and noise performance. The tyre labels are similar to the labelling already in use for household goods such as washing machines and dishwashers.  Each tyre will be given a performance rating from A-G excluding D to avoid an average performing tyre.

Driving hazards at this time of year

 Sun Blindness or Sunstrike

Sunstrike can occur at any time during the day, but is most likely during sunrise or sunset, when the sun’s rays hit your windscreen at a low angle.
To avoid a crash, follow the simple guidelines shown below.

Reducing the danger of sunstrike

• Be prepared for possible sunstrike when driving at sunrise or sunset, especially when turning or driving towards the sun.
• Be especially careful in the autumn and winter months, when sunstrike is more likely to occur because the sun is lower in the sky.
• Keep your windscreen clean, inside and out. Dust and dirt on the windscreen can make the effects of sun blindness much worse.
• Check your windscreen washer container and top up if necessary.
• Always carry a cloth in your car for cleaning the windscreen.
• Wear sunglasses when driving with the sun in your eyes.
• Use your car's sun visors to block the sun.
• If you experience sunstrike, it may be best to pull over and wait for a few minutes until your eyes adjust or visibility improves. Remember if you can't see where you are going: Stop.
• Be careful if snow has fallen and the sky is clear – sunlight shining on snow can cause 'snow blindness', which produces similar effects to sunstrike.

Hazards for this time of year

Be careful when driving in bright sunlight at this time of  the year. You may suddenly find your vision of the road ahead very diminished. This can happen early in the morning or early evening when the Sun is low. Slow or stop if necessary and remember that if can't see where you are going then don't go: Stop. Before you start your journey make sure windows are clean inside and out. Check the water in  the windscreen washer container and top if necessary. Always have a cloth for cleaning the window on the inside, and use heater controls to keep the window from misting up.

Replacing Light bulbs

You know when one bulb blows a few more are going to go within a few weeks. Well this is the case with me anyway. Now I don't have a problem with this as their life span should be similar.
What really annoys me is the time it now takes to replace one of those bulbs. I am pretty sure that the so called engineer or designer that designed the lamps and their positioning has never had the pleasure of replacing a bulb once the units are on the car.
Now this is not a new problem, I owned a Fiat Punto and you needed the wheel brace to open a bolt when you wanted to replace a brake light bulb. I think it took about a half an hour to replace a brake light bulb on a Fiesta. This was a major problem when you had someone doing a driving test and the bulb blowing just before the test. It is a bigger problem now as the driving tester won't take someone out on a test if the two side brake lights are not working.
Anyway the reason for my gripe tonight is I am just after replacing a headlight bulb on a Peugeot 308 passenger side. It was cold and freezing and you would need to be double jointed to get at the bulb. No right view so you can't see what you are doing, and then trying to get the clips off. When it is finally removed you now have to figure out where the groove is for the bulb to sit back into. You might say why didn't you look at it as it was coming out, that would have been a good idea. The only problem with this; you can't look and contort yourself at the same time. Again about a half hour's work.
Ok so maybe I am getting too old for this or my hands are not as flexible as they used to be, but I am still of the opinion that the design is what the problem is.
Let me know if you agree or disagree, I will be interested in your opinion.

Road Design on Boyle to Sligo Road At Castlebaldwin
Now I am not an engineer, but I am someone who uses the roads quite a lot. I have travelled on the Boyle to Sligo (N4)every week over the last few years. I was delighted when Sligo County council or the NRA started to work on the the section after Castlebaldwin on the Sligo side. It is definately a major improvement on the road that was already there. I think it is due to finish shortly as they are working on the sides and generally tidying up.
But here comes my gripe: When coing from Sligo there is a turn off to the right and on the main carraigeway there is an arrow for straight ahead and an arrow to turn off right. So far so good you might say, but there is no room for a car to move out to the right they are still on the main carraigeway. Now what really is annoying is that there is a massive amount of a hard shoulder on the left. So why could they not have made the road with a lane to turn right and use some of or all of the hard shoulder for traffic going straight on? Who is getting paid to do a design like this?
Some years back when the Curlew bypass was built a similiar problem existed. If you were coming from Carrick-on-Shannon towards Sligo and wanted to turn off for Ballyfarnon you had to move out to the overtaking lane and wait in it to turn right, if traffic was coming from Sligo. A lethal situation. It took a few years for them to change the layout of that juntion, all they needed to do was to change road markings.
Maybe the same designer is involved with this road design at Castebaldwin.

Be aware of the Silent Killer

A new silent killer is now on our roads, it is the new electric cars. When moving off from a parked position and especially in carparks there will be no noise from the electric cars. This can pose a major danger to pedestrians as the walk through the carpark. Just think of you pushing a trolley with wonky wheels and your children running around you, and suddenly a car starts moving out of a space; no warning of an engine starting. I know you could say that the driver should be looking out for me and mine but this is not always the case. Maybe by next year some standards should be in force so that all electric cars will have some form of audible sound before they stat to move.
International standards, which have already been drawn up by the United Nations Economic Commission for Europe, are expected to be turned into legally binding regulations by the end of next year.

The move comes as the popularity of fuel-efficient hybrid and electric cars grows, as motorists look to tackle soaring petrol and diesel costs.

According to the latest industry figures there are currently 2,353 electric and 128,165 hybrid cars – such as the best selling Toyota Prius – on Britain’s roads. I am not sure what the figure here is in Ireland at the moment. 

Research carried out last year by TRL, formerly the Government’s Transport Research Laboratory, found taking into account the number of vehicles on the road, pedestrians were more likely to be hit by an electric car than a conventional one.

It also found electric and hybrid cars were quieter than conventional vehicles in the first five metres after a standing start, such as at a pedestrian crossing.

Car Design for Road Safety

For the last twelve months or more there is something that has been bothering me about new cars. It really came to me in a very real way yesterday morning as I travelled to Dublin. The problem is the position and colour of Indicator signals on modern cars.
It is possibly a style problem,or maybe a cost problem that manufacturers are placing their indicators in the same assembly as the headlights. This makes it impossible to see the indicators working when the lights are on. This also applies in the day time when the vehicle has dipped lights on.
This is now becoming a problem at the rear as well. Some cars have their indicators in the middle of the brake lights. All of this looks lovely of course, but not at all practical and definately not safe. Another gripe I have is the placing of the side indicators in the wing mirrors. I think that the people in charge of granting Type Approval to vehicles should take a closer look at how cosmetic changes are affecting road safety.
Maybe I am alone in my thinking but I would like to hear from anyone else who thinks the same. I intend to do a survey of cars that I feel are posing a safety risk.
