It is dangerous to ignore a Warrant / Arrest Warrant as it may end up landing you in jail or making you liable for huge fine. Arrest warrants may be issued against you for trivial offences such as non payment of parking fee which you may have done in ignorance. It is advisable to make arrest warrants search regularly so as to find out if you have any active arrest warrant against you.
Making an arrest warrant search by visiting the local police station and checking police arrest records where you feel the warrant may have been issued is dangerous as the police may arrest you on the spot as soon as they find that a warrant is pending against you.
It is better to make online arrest warrant search so that if you find that an arrest warrant is issued against you, you may immediately hire a lawyer for defending you. Alternatively, you may also visit the local courthouse and search arrest public record physically.
An effective arrest warrant search can be made with the help of websites such as this one offering online search for arrest warrants.
