[(1) A police officer in uniform or an officer of the Motor Vehicles Department, as may be authorised in this behalf by that Department, may require any person driving or attempting to drive a motor vehicle in a public place to provide one or more specimens of breath for breath test there or nearby, if such police officer or officer has any reasonable cause to suspect him of having committed an offence under section 185:

Provided that requirement for breath test shall be made (unless it is made) as soon as reasonably practicable after the commission of such offence.]

(2) If a motor vehicle is involved in an accident in a public place and a police officer in uniform has any reasonable cause to suspect that the person who was driving the motor vehicle at the time of the accident had alcohol in his blood or that he was driving under the influence of a drug referred to in section 185 he may require the person so driving the motor vehicle, to provide a specimen of his breath for a breath test

(a) in the case of a person who is at a hospital as an indoor patient, at the hospital,

(b) in the case of any other person, either at or near the place where the requirement is made, or, if the police officer thinks fit, at a police station specified by the police officer

Provided that a person shall not be required to provide such a specimen while at a hospital as an indoor patient if the registered medical practitioner in immediate charge of his case is not first notified of the proposal to make the requirement or objects to the provision of a specimen on the ground that its provision or the requirement to provide it would be prejudicial to the proper care or treatment of the patient.

(3) If it appears to a police officer in uniform, in consequence of a breath test carried out by him on any person under sub-section (1) or sub-section (2), that the device by means of which the test has been carried out indicates the presence of alcohol in the persons blood, the police officer may arrest that person without warrant except while that person is at a hospital as an indoor patient.

(4) If a person, required by a police officer under sub-section (1) or sub-section (2) to provide a specimen of breath for a breath test, refuses or fails to do so and the police officer has reasonable cause to suspect him of having alcohol in his blood, the police officer may arrest him without warrant except while he is at a hospital as an indoor patient.

(5) A person arrested under this section shall while at a police station, be given an opportunity to provide a specimen of breath for a breath test there.

(6) The results of a breath test made in pursuance of the provisions of this section shall be admissible in evidence.

Explanation.— For the purposes of this section, "breath test" means a test for the purpose of obtaining an indication of the presence of alcohol in a person's blood carried out, on one or more specimens of breath provided by that person, by means of a device of a type approved by the Central Government, by notification in the Official Gazette, for the purpose of such a test.

Legal Commentary & Landmark Judgments: Section 203

Section 203 of the Motor Vehicles Act, 1988 provides the statutory machinery for administering preliminary breath tests using breathalysers to detect drunken driving, establishing that refusal to submit to a breath test constitutes an arrestable offence and creates an adverse evidentiary inference.

Statutory Mandate for Breathalyser Screening: Section 203(1) empowers a police officer in uniform or an authorized Motor Vehicles Department officer to require any driver or person in charge of a motor vehicle to provide a specimen of breath for a breath test on reasonable suspicion of alcohol consumption or post-accident.
Location and Timing of Breath Test: Section 203(2) mandates that the breath test shall be administered as soon as reasonably practicable, either at or near the scene of the vehicular interception, or at a nearby police station or hospital.
Penal Consequences of Breath Test Refusal: Section 203(3) and (4) establish that if a driver refuses or fails to provide a breath specimen without reasonable excuse, the police officer is statutorily authorized to arrest the driver without warrant under Section 202 and require a laboratory blood test under Section 204.

Key Landmark Precedents:

Alistair Anthony Pareira v. State of Maharashtra (2012) 2 SCC 648: The Supreme Court underscored the vital evidential value of breathalyser tests and blood tests under Sections 203 and 204 in drunken driving prosecutions, holding that driving while intoxicated with knowledge of potential devastation satisfies Section 304 Part II IPC.
Sanil Kumar v. State of Kerala, 2020 SCC OnLine Ker 2231: The Kerala High Court held that breath analysis under Section 203 must be conducted using certified, properly calibrated breathalysers; a printed digital slip reflecting exact blood alcohol concentration (BAC) is essential to sustain prosecution under Section 185.

Courtroom Practice & Strategic Litigation Guidance:

In defending drunken driving prosecutions, demand the calibration certificate and maintenance logs of the breathalyser device used under Section 203. If the device was uncalibrated, expired, or lacked a contemporaneous digital printout showing the exact BAC measurement, the prosecution under Section 185 cannot be sustained on oral testimony alone.
