Uniform speed
z Hectic d riv ing significantly increases the
noise level, the quantity of em ission a nd
the proportion of p ollutant in the
exhaust.
z Do not a ccelerate and brake
unnecessarily. Drive at uniform speed.
Driv ing in top gear a s m uc h as p ossible,
driv ing in 4th or 5th gear from a speed of
30 mph (50 km/h) in urba n tra ffic,
shifting up as soon as possible and not
shifting down until the engine is no
longer running smoothly considerably
reduces the amount of noise pollution.
Urban traffic
z Freq uent driving off and stopping – for
exam ple a t traffic lig hts – greatly
increases the noise level.
z Av oid unnecessa ry stop s b y alway s
anticipa ting the driving conditions
ahead.
If possible, selec t roa ds with a good
traffic flow.
Keep a safe dista nce from the vehicle in
front and av oid unnecessary brak ing
and acceleration.
Driv e considerately, esp ecially in
resid ential areas and particularly at
night.
High s peed
z Driving at full throttle generates
excessive noise and em ission. Tyre and
wind noise also increases considerably
as the speed increases. Tyre noise
determines the overall vehicle noise level
in the highest g ear from speeds of
45 mph (70 k m/h). A vehicle driving at
90 mph (150 km /h) generates as much
noise as four vehicles d riv ing at
90 mph (100 km /h) or ten driv ing at 45
mph (70 km/h).
z Avoid trav elling at high speeds by
carefully planning your journey s.
Doors
z Slam ming doors create noise.
z C lose doors quietly . Be considerate,
especially in residential areas and
particularly a t nig ht.
The first 600 miles/1 000 km
z Technically incorrect and uneconomical
driving will impa ir the performa nce of
your vehicle and shorten its service life.
z Driv e y our vehicle sm oothly, making
good use of the gears as speeds c hange.
Depress the accelerator peda l a
maxim um of around three q uarters of
the a vailable pedal trav el. Do not use full
throttle,
Do not drive faster than three quarters of
maxim um sp eed. ,
Never a llow the engine to labour at low
revs.
