Almost half of inspected taxi drivers are breaking the law and other regulations. One of the most common offences is overcharging of customers through not correctly informing about price. Other offences include incorrect charging of extra fees and supplements and using some crooked business practices. This data comes from the Czech Trade Government Inspection office from 144 randomly checked cabbies during the first quarter of 2009. The inspection also discovered that one of the drivers used an illegal taxi meter, which resulted in inflated taxi fares. One “positive” figure is that the city of Prague is not the worst in the chart. In Prague, out of 43 cabbies, 16 violated the law, but in some regions like South Bohemia and Vysocina the statistics are even worse (from 12 cabbies, 10 failed).
Tip: Avoid taxis around the main tourist sights, these can often be the worst offenders. Few taxi drivers speak more than the most rudimentary English, so communication can be difficult. Unless your Czech pronunciation is good, write down your destination for them in Czech or pre book taxi online.
