The reduction should be much more as petrol ( unlike diesel ) is mainly used by the common man ( in scooters , motorcycles , Maruti 800 , Nano etc. ) Expensive vehicles use diesel. Due to Vote Bank politics diesel prices are not touched . This leaves the common man to bear the burden of rich man's luxuries.
Petrol price in Punjab is around Rs. 7 a Liter more expensive than in Haryana
There are heavy taxes on Petrol . The actual cost of Petrol is less than Rs. 25 Per Litre.
So the reduction in Petrol price in Punjab should be Rs. 10 + Per Litre
Further , Maruti 800 , Nano cars and Physically Handicapped travelers should be exempted at the Toll Plazas on the Highways.
