Law and Field Use of the Alcotest 7410 GLC

The use of approved screening devices in

Canada is governed by the Criminal Code.

The user should be familiar with those

sections of the Code that deal with approved

screening devices and drinking-driving in

general. There is also operational policy in

place to ensure a uniform approach to

drinking-driving enforcement throughout

the province. This section discusses the law

and policy related to the use of ASDs.

Although this manual deals with the

Alcotest 7410 GLC, the law and policy are

the same for all ASDs.

A. Criminal Code Sections

The sections dealing with the use of ASDs

are listed below. These sections should be

well known to peace officers who have been

involved in previous drinking-driving

investigations. They are reviewed here for

completeness and continuity.

Section 253(1)(a) C.C. - 

the offence of

impaired driving.

Section 253(1)(b) C.C. -

 the offence of

exceeding 80 milligrams of alcohol in

100 millilitres of blood.

Section 254(1) C.C. - 

definitions section for

the drinking-driving offences.

“approved screening device” means a
device of a kind that is designed to
ascertain the presence of alcohol in

the blood of a person and that is
approved for the purposes of this
section by order of the Attorney
General of Canada;

The key here is that before any screening

device can be used, it must be 

approved

 for

use and appear on the 

Approved Screening

Devices Order.

 The Alcotest 7410 GLC is

included on this order and is therefore

approved for use. For court purposes, the

user must know exactly which device and

model was used.

Section 254(2)(b) C.C. - 

the demand

section for an ASD.

This section gives the peace officer the

authority to 

demand 

a breath sample for

analysis by an ASD on reasonable suspicion

that the person has alcohol in the body.

Section 254(3)(a)(i) C.C. - 

the demand

section for a breath sample into an

approved instrument.

Before this demand is made, there must be

reasonable grounds to believe a person has

committed an offence under Sec. 253 C.C.

within the previous three hours. It is here

that the peace officer uses the results from

the ASD test taken under Section 254(2)(b)

C.C.. The “F” (FAIL) indication on the

ASD means the BAC exceeds 80 mg% and

thus provides the reasonable grounds to

believe that the person has committed an
