  (1) The Administrator may, by notification in the Official Gazette, set up check-posts or barriers, or both, at any place in Delhi with a view to preventing evasion of tax and other dues payable under this Act.
  (2) The owner or person in charge of a goods vehicle shall carry with him a goods vehicle record, a trip sheet or a log book, as the case may be, and a bill of sale or a delivery note containing such particulars as may be prescribed in respect of the goods carried in the goods vehicle and produce the same before any officer in charge of a check-post or barrier or any other officer as may be empowered by the Administrator in this behalf.
  (3) The owner or person in charge of a goods vehicle entering or leaving Delhi shall also file a declaration containing such particulars in the prescribed form obtainable from the prescribed authority and in such manner as may be prescribed, before the officer in charge of a check-post or barrier or before the other officer empowered as aforesaid:
  Provided that where the owner or person in charge of a goods vehicle after filing a declaration at the time of entering Delhi that the goods are meant to be carried to a place outside Delhi, fails, without reasonable cause, to carry such goods outside Delhi within the prescribed period, he shall, in addition to the payment of tax, if any, be liable to a penalty not exceeding two and a half times the tax that would have been payable had the goods been sold inside Delhi or one thousand rupees, whichever is more.
  (4) At every check-post or barrier, or at any other place when so required by an officer empowered by the Administrator in this behalf, the driver or any other person in charge of a goods vehicle shall stop the vehicle and keep it stationary so long as may be required by the officer in charge of the check-postor barrier or the officer empowered as aforesaid to search the goods vehicle or part thereof, examine the contents therein and inspect all records relating to the goods carried, which are in the possession of such driver or other person in charge, who shall, if so required, give his name and address and the name and address of the owner of the vehicle as well as those of the consignor and consignee of the goods.
  (5) If on an examination of the contents in a goods vehicle or the inspection of records relating to the goods carried, any officer empowered by the Administrator in this behalf has reason to believe that the owner or person in charge of such goods vehicle is attempting to evade payment of the tax due under this Act, he may, for reasons to be recorded in writing and after hearing the owner or person in charge of the goods vehicle, detain the goods and the goods so detained shall not be allowed to be transported unless the owner, or his agent or the person in charge of the goods vehicle furnishes to the satisfaction of such officer security in such form and in such manner as may be prescribed for an amount not exceeding one thousand rupees or the amount of tax payable if such goods were sold in Delhi, whichever is more.
  (6) Where the security required to be furnished under sub-section (5) is not furnished within the prescribed period such goods shall be disposed of in such manner and subject to such conditions as may be prescribed.
